Stephen is testing the difference in means between time it takes to travel school in a bus and time it takes to travel to school in a car. Stephen hypothesizes that it takes more time to travel in a bus. He calculates a p-value of 2%. He concludes at a 1% significance level that the true mean is greater for a bus than a car.
Where did Stephen go wrong in his conclusion? Explain in detail.
Answer:
Kindly check explanation
Step-by-step explanation:
To test for Difference in mean times
Null hypothesis, H0 will be, there is no difference in mean times ; m1 = m2
Alternative hypothesis, there is difference in mean times ; m1 ≠ m2
Decision region :
When p value < α ; reject the Null
Here. ;
Pvalue = 2% = 0.02
α = 1% = 0.01
Pvalue > α
0.02 > 0.01
Since, Pvalue > α ; we do not reject the Null ;
Hence, conclusion should be, there is no difference in mean times of bus and car

2. Lena can finish 2 math homework problems in 15 minutes. At this rate, how many problems can she finish in 75 minutes? Use the rate table below to find the answer.
10.
Because the ratio is how many problems:How much time so it is 2:15
Multiply each side by 5 10:75
So that means 10 problems in 75 minuets.
HOPE THIS HELPED!!!
Answer:
10
Step-by-step explanation:
Set up the following proportion.
2 questions /15 minutes = x questions / 75 minutes.
Notice that both ratios are set up the same way -- questions / time. All proportions are set up the same way.
Mulltiply both sides by 75
2 * 75 / 15 = x
2 * 5 = x
x = 10
She would be able to solve 10 problems in 75 minutes.

Find value of x pleaseee
Answer:
Step-by-step explanation:
you can use the side angle side formula ( a form of Law of Cosines)
a^2 = b^2 + c^2 − 2bc cos(A)
where x = a , then
[tex]x^{2}[/tex] = [tex]5^{2}[/tex] +[tex]3^{2}[/tex] - 2*5*3*cos(107)
[tex]x^{2}[/tex] = 25 + 9 - 30 * (-0.292371)
[tex]x^{2}[/tex] = 25 + 9 -8.7711511
x = 5.0228 cm

find the missing angle measures of the following figure
Answer:
1 = 68
2 = 68
3 = 125
Step-by-step explanation:
Hey there!
To find angle 1 all we have to do is subtract the given angles from 180 because remember all of the angles in a triangle add up to 180
180-73-39=68
1=68
angle 2 is vertical to angle 1 therefore they are congruent angles so
2 also equals 68
So we know that the interior angles in a 4 sided shape add up to equal 360
so to find 3 we subtract the given angles from 360
360-90-77-68=125
so 3 = 125

The student council has $800 to spend on homecoming t-shirts. The number of t-shirts they can buy is a function of the price of the price of the t-shirt p, in dollars, given by n(p)= 800 over p. As p gets larger and larger, what does the end behavior of the function tell you about the situation? *
Answer:
n will get lower and lower
Step-by-step explanation:
In this equation the number of shirts is being multiplied by the price of each individual shirt and ultimately equals a total of $800. This means that the total must always be equal to $800 and cannot surpass it or be blow this value. Therefore, if the value of p gets larger and larger the less the number of shirts (n) that the students will be able to buy. This is the only way for the total cost to remain steady.
A spinner with 9 equal sections is numbered 1 through 9. The probability of spinning a 3 is 1/9. What is the probability of not spinning a 3? Enter your answer as a fraction, in simplest form, in the box.
Answer:
The probability of not spinning a 3 is [tex]\frac{8}{9}[/tex]
Step-by-step explanation:
The probability of spinning a 3 is 1/9. What is the probability of not spinning a 3?
Spinning a 3 and not spinning a 3 are complementary events, which means that the sum of their probabilities is decimal 1. So
[tex]\frac{1}{9} + p = 1[/tex]
[tex]p = 1 - \frac{1}{9} = \frac{9}{9} - \frac{1}{9} = \frac{8}{9}[/tex]
The probability of not spinning a 3 is [tex]\frac{8}{9}[/tex]

total degree inside pentagon is (n - 2) x 180 = 540
180-62 = 118
180-66 = 114
180-77 = 103
180-59 = 121
118+114+103+121 = 456
540 - 456 = 84
84 + 12x = 180
12x = 180-84
x = 96/12
x = 8
The value of x in the given pentagon is 8.
Option D is the correct answer.
What is a Pentagon?A pentagon is a polygon that has five sides and five angles.
The sides and angles of a pentagon are not all equal unless it is a regular pentagon.
A regular pentagon has five equal sides and five equal angles.
We have,
For a pentagon, n = 5, so we have:
total degree = (5 - 2) × 180 degrees
total degree = 3 × 180 degrees
total degree = 540 degrees
Now,
Each angle makes a straight angle.
So,
77 + a = 180
a = 180 - 77 = 103
59 + b = 180
b = 180 - 59 = 121
c + 66 = 180
c = 180 - 66 = 114
d + 62 = 180
d = 180 - 62 = 118
Now,
a + b + c + d + e = 540
103 + 121 + 114 + 118 + e = 540
e = 540 - 456
e = 84
Now,
12x + 84 = 180
So,
12x = 180 - 84
12x = 96
x = 8
Thus,
The value of x is 8.

Step-by-step explanation:
You may borrow up to 2.5 times your annual income. Arianna is buying a home. Her weekly income is $900. What is the maximum amount that she may borrow?
Answer: $117,000
Step-by-step explanation:
The maximum that Arianna may borrow is 2.5 times her annual income.
First step therefore, would be to calculate her annual income:
= 900 * 52 weeks
= $46,800
She may borrow 2.5 times this:
= 46,800 * 2.5
= $117,000
2. The box plots summarize the number of students at the fall and spring dances. Which statement best describes the data represented in the box plots?
Answer:
See Explanation
Step-by-step explanation:
The question has missing parameters, as the box plot is not given.
So, I will answer the question using the attached box plot.
Basically, the box plot summarizes 5 data which are:
Minimum, Lower quartile, the Median, the Upper quartile and the Range
So, the summary is as follows:
The first dot on the box plot represents the minimum
[tex]Minimum = 2[/tex]
The first line represents the lower quartile
[tex]Q_1 = 3[/tex]
The mid-line represents the median:
[tex]Q_2 = 6[/tex]
The third line represents the upper quartile:
[tex]Q_3 = 8[/tex]
The last dot represents the maximum
[tex]Maximum = 12[/tex]
From the above data, we can also calculate the range.
[tex]Range = Maximum - Minimum[/tex]
[tex]Range = 12 - 2[/tex]
[tex]Range = 10[/tex]
