Shall we reject or not reject the claim that there is no difference in the population mean three-circle red-on-white sherd counts for the four sites? Use a 5% level of significance.
Answers
Answer:
Step-by-step explanation:
Hello!
The objective is to test if the population mean of three-circle red-on-white sheds is equal to the four excavation sites.
To compare the population means you have to apply an ANOVA. For this test the variable of interest is
X: number of three-circle red-on-white sheds.
There is only one factor: "Site" with four treatments "I, II, III; IV"
H₀: μ₁= μ₂= μ₃= μ₄
H₁: At least one population mean is different.
α: 0.05
[tex]F= \frac{MS_{Treatment}}{MS_{Error}} ~~F_{K-1;N-K}[/tex]
Df treatments: k-1= 4-1= 3 (k= nº of treatments)
Df errors: N-K= 21-4= 17 (N= total observations for all treatments)
[tex]F_{H_0}= \frac{102.72}{117.08}= 0.88[/tex]
p-value: 0.4723
Using the p-value approach the decision rule is:
p-value ≤ α, reject the null hypothesis.
p-value > α, do not reject the null hypothesis.
The p-value is greater than the level of significance, the decision is to reject the null hypothesis.
Using a 5% significance level, there is not significant evidence to reject the null hypothesis. Then you can conclude that the population mean three-circle red-on-white sherd count is equal to all the excavation sites.
I hope this helps!

A ball thrown into the air from a roof 15 feet above the ground with an initial vertical velocity of 30 ft/sec can be modeled by the equation: . How long will the ball be in the air? What is it’s maximum height?
Answers
Answer:
Total time of flight= 6.3 s
Total Max height= 60.87ft
Step-by-step explanation:
Height above ground = 15ft
Velocity=30ft/sec
Angle = 90°
Max height traveled= U²Sin²tita/2g
Max height traveled= ( 30²*1²)/(2*9.81)
Max height traveled= 900/19.62
Max height traveled= 45.87 ft
Total Max height= 15+45.87= 60.87ft
Time travel to Max height
=( usin90)/g
Time travel to initial position
= (30*sin90)/9.81
= 3.1 s
Time to travel to the ground from Max height
H = 1/2gt²
60.87= 1/2 * 9.81*t²
(60.87*2)/9.81= t²
3.5 = t

Answer:
12(cos120°+isin120°)Step-by-step explanation:
The rectangular form of a complex number is expressed as z = x+iy
where the modulus |r| = [tex]\sqrt{x^{2}+y^{2}[/tex] and the argument [tex]\theta = tan^{-1}\frac{y}{x}[/tex]
In polar form, x = [tex]rcos\theta \ and\ y = rsin\theta[/tex]
[tex]z = rcos\theta+i(rsin\theta)\\z = r(cos\theta+isin\theta)[/tex]
Given the complex number, [tex]z = -6+6\sqrt{3} i[/tex]. To express in trigonometric form, we need to get the modulus and argument of the complex number.
[tex]r = \sqrt{(-6)^{2}+(6\sqrt{3} )^{2}}\\r = \sqrt{36+(36*3)} \\r = \sqrt{144}\\ r = 12[/tex]
For the argument;
[tex]\theta = tan^{-1} \frac{6\sqrt{3} }{-6} \\\theta = tan^{-1}-\sqrt{3} \\\theta = -60^{0}[/tex]
Since tan is negative in the 2nd and 4th quadrant, in the 2nd quadrant,
[tex]\theta =180-60\\\theta = 120^{0}[/tex]
z = 12(cos120°+isin120°)
This gives the required expression.

In which
[tex]x_{v} = -\frac{b}{2a}[/tex]
If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]f(x_{v})[/tex]
In this question:
[tex]h(t) = -32t^{2} + 8t + 3[/tex]

Solve this equation for x: 2x^2 + 12x - 7 = 0
What is the first step to solve this equation?
-combine like terms
-factor the trinomial
-isolate the constant term by adding 7 to both sides
Answers
Answer:
x=0.5355 or x=-6.5355
First step is to: Isolate the constant term by adding 7 to both sides
Step-by-step explanation:
We want to solve this equation: [tex]2x^2 + 12x - 7 = 0[/tex]
On observation, the trinomial is not factorizable so we use the Completing the square method.
Step 1: Isolate the constant term by adding 7 to both sides
[tex]2x^2 + 12x - 7+7 = 0+7\\2x^2 + 12x=7[/tex]
Step 2: Divide the equation all through by the coefficient of [tex]x^2[/tex] which is 2.
[tex]x^2 + 6x=\frac{7}{2}[/tex]
Step 3: Divide the coefficient of x by 2, square it and add it to both sides.
Coefficient of x=6
Divided by 2=3
Square of 3=[tex]3^2[/tex]
Therefore, we have:
[tex]x^2 + 6x+3^2=\frac{7}{2}+3^2[/tex]
Step 4: Write the Left Hand side in the form [tex](x+k)^2[/tex]
[tex](x+3)^2=\frac{7}{2}+3^2\\(x+3)^2=12.5\\[/tex]
Step 5: Take the square root of both sides and solve for x
[tex]x+3=\pm\sqrt{12.5}\\x=-3\pm \sqrt{12.5}\\x=-3+ \sqrt{12.5}, $ or $x= -3- \sqrt{12.5}\\$x=0.5355 or x=-6.5355[/tex]

The time, T (seconds) it takes for a pot of water to boil is inversely proportional to the cooker setting, H , applied to the pot. When H = 7 , T = 150 . What must the cooker setting be if it takes 7 minutes to boil the water?
Answers
Answer:
150
Step-by-step explanation:
Given the following parameters;
Time, T = 150mins
Cooker setting, H = 7
Since the time for a pot of water to boil is inversely proportional to the cooker setting;
[tex]T * 1/H[/tex]
[tex]T = K/H[/tex] ........equation 1
Where, K is the constant of proportionality.
Substituting the parameters into the equation 1, we have;
150 = K/7
K = 150*7
K = 1050
To find the cooker setting at 7mins;
[tex]T = K/H[/tex]
H = K/T
H = 1050 ÷ 7
H = 150.
Hence, the cooker setting must be at 150.

We assume your intended attendance equation is ...
A = -1.95x^3 +70.1x^2 -188x +2150
a. For x=0 (corresponding to 1985), the first three terms are 0, so we have ...
A = 2150 . . . . the initial value of the function
__
b. For x=13 (corresponding to 1985) we have ...
A = ((-1.95(13) +70.1)(13) -188)(13) +2150 = (44.75(13) -188)(13) +2150
= 393.75(13) +2150 = 7268.75
Attendance in the year 1998 is modeled to be about 7269.

In October 2012, Apple introduced a much smaller variant of the Apple iPad, known as the iPad Mini. Weighing less than 11 ounces, it was about 50% lighter than the standard iPad. Battery tests for the iPad Mini showed a mean life of 10.25 hours (The Wall Street Journal, October 31, 2012). Assume that battery life of the iPad Mini is uniformly distributed between 8.5 and 12 hours.
a. What is the probability that the battery life for an iPad Mini will be 10 hours or less (to 4 decimals)?b. What is the probability that the battery life for an iPad Mini will be at least 11 hours (to 4 decimals)?c. What is the probability that the battery life for an iPad Mini will be between 9.5 and 11.5 hours (to 4 decimals)?d. In a shipment of 100 iPad Minis, how many should have a battery life of at least 9 hours (to nearest whole value)?
Answers
Answer:
a) 0.4286 = 42.86% probability that the battery life for an iPad Mini will be 10 hours or less
b) 0.2857 = 28.57% probability that the battery life for an iPad Mini will be at least 11 hours
c) 0.5714 = 57.14% probability that the battery life for an iPad Mini will be between 9.5 and 11.5 hours
d) 86 should have a battery life of at least 9 hours.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X lower than x is given by the following formula.
[tex]P(X \leq x) = \frac{x - a}{b-a}[/tex]
The probability of being higher than x is:
[tex]P(X > x) = \frac{b - x}{b-a}[/tex]
The probability of being between c and d is:
[tex]P(c \leq X \leq d) = \frac{d-c}{b-a}[/tex]
Assume that battery life of the iPad Mini is uniformly distributed between 8.5 and 12 hours.
This means that [tex]a = 8.5, b = 12[/tex]
a. What is the probability that the battery life for an iPad Mini will be 10 hours or less (to 4 decimals)?
[tex]P(X \leq x) = \frac{x - a}{b-a}[/tex]
[tex]P(X \leq 10) = \frac{10 - 8.5}{12 - 8.5} = 0.4286[/tex]
0.4286 = 42.86% probability that the battery life for an iPad Mini will be 10 hours or less.
b. What is the probability that the battery life for an iPad Mini will be at least 11 hours (to 4 decimals)?
[tex]P(X > x) = \frac{b - x}{b-a}[/tex]
[tex]P(X > 11) = \frac{12 - 11}{12 - 8.5} = 0.2857[/tex]
0.2857 = 28.57% probability that the battery life for an iPad Mini will be at least 11 hours
c. What is the probability that the battery life for an iPad Mini will be between 9.5 and 11.5 hours (to 4 decimals)?
[tex]P(c \leq X \leq d) = \frac{d-c}{b-a}[/tex]
[tex]P(9.5 \leq X \leq 11.5) = \frac{11.5 - 9.5}{12 - 8.5} = 0.5714[/tex]
0.5714 = 57.14% probability that the battery life for an iPad Mini will be between 9.5 and 11.5 hours.
d. In a shipment of 100 iPad Minis, how many should have a battery life of at least 9 hours (to nearest whole value)?
Proportion of iPad Minis with a battery life of at least 9 hours.
[tex]P(X > 11) = \frac{12 - 9}{12 - 8.5} = 0.8571[/tex]
Out of 100:
0.8571*100 = 85.71
To the nearest whole number
86 should have a battery life of at least 9 hours.

Some parts of California are particularly earthquake-prone. Suppose that in one metropolitan area, 33% of all homeowners are insured against earthquake damage. Four homeowners are to be selected at random. Let X denote the number among the four who have earthquake insurance. A) Find the probability distribution of X.B) What is the most likely value for X?
C) What is the probability that at least two of the four selected have earthquake insurance?
Answers
Answer:
(a) The probability mass function of X is:
[tex]P(X=x)={4\choose x}\ (0.33)^{x}\ (1-0.33)^{4-x};\ x=0,1,2,3...[/tex]
(b) The most likely value for X is 1.32.
(c) The probability that at least two of the four selected have earthquake insurance is 0.4015.
Step-by-step explanation:
The random variable X is defined as the number among the four homeowners who have earthquake insurance.
The probability that a homeowner has earthquake insurance is, p = 0.33.
The random sample of homeowners selected is, n = 4.
The event of a homeowner having an earthquake insurance is independent of the other three homeowners.
(a)
All the statements above clearly indicate that the random variable X follows a Binomial distribution with parameters n = 4 and p = 0.33.
The probability mass function of X is:
[tex]P(X=x)={4\choose x}\ (0.33)^{x}\ (1-0.33)^{4-x};\ x=0,1,2,3...[/tex]
(b)
The most likely value of a random variable is the expected value.
The expected value of a Binomial random variable is:
[tex]E(X)=np[/tex]
Compute the expected value of X as follows:
[tex]E(X)=np[/tex]
[tex]=4\times 0.33\\=1.32[/tex]
Thus, the most likely value for X is 1.32.
(c)
Compute the probability that at least two of the four selected have earthquake insurance as follows:
P (X ≥ 2) = 1 - P (X < 2)
= 1 - P (X = 0) - P (X = 1)
[tex]=1-{4\choose 0}\ (0.33)^{0}\ (1-0.33)^{4-0}-{4\choose 1}\ (0.33)^{1}\ (1-0.33)^{4-1}\\\\=1-0.20151121-0.39700716\\\\=0.40148163\\\\\approx 0.4015[/tex]
Thus, the probability that at least two of the four selected have earthquake insurance is 0.4015.

We can rewrite the last expression like this if we multiply both sides of the equation by -1.
[tex] y^2 -4y +6=0[/tex]
Now we can use the quadratic formula given by:
[tex] y =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]
Where [tex] a = 1, b= -4 ,c =6[/tex]
And replacing we got:

14x = 90+8
14x = 98
Dividing both sides by 14
x = 7
