A chi-square test of independence was conducted to investigate whether there is an association between the location where a person lives in a city (north, south, east, or west) and who the person planned to vote for in the upcoming mayoral election (the incumbent or the challenger). A random sample of 100 potential voters was selected, and the hypothesis test had a chi-square test statistic of χ2=9.84 with a p-value of 0.02. Which of the following statements is the correct interpretation of the p-value in context?
(A) There is a 2 percent chance that where a person lives and who that person plans to vote for are independent.
(B) There is a 2 percent chance that where a person lives and who that person plans to vote for are dependent.
(C) There is a 2 percent chance of making a Type II error.
(D) Assuming that the location of where a person lives and who that person plans to vote for are dependent, there is a 2 percent chance of finding a test statistic that is 9.84 or greater.
(E) Assuming that the location of where a person lives and who that person plans to vote for are independent, there is a 2 percent chance of finding a test statistic that is 9.84 or greater.
Answer:
E) Assuming that the location of where a person lives and who that person plans to vote for are independent, there is a 2 percent chance of finding a test statistic that is 9.84 or greater.

1Alfred departs from NAMPO Park
at 18:45 and travels to Sasolburg at
an average speed of 88 km/h. He
calls his wife to inform her that he
will arrive in Sasolburg at 8 pm.
Verify, with calculations, whether his
estimate is correct.
You may use the formula:
Distance= Speed x time
Answer:
Alfred will not arrive in his city at 8 PM, but he will arrive at approximately 8:20 PM.
Step-by-step explanation:
Since Alfred departs from NAMPO Park at 18:45 and travels to Sasolburg at an average speed of 88 km / h, and he calls his wife to inform her that he will arrive in Sasolburg at 8 pm, to determine if his estimate is correct the following calculations must be performed:
The shortest route from Nampo Park to Sasolburg in South Africa is 139 km via Route 59.
8 PM = 20:00
20:00 - 18:45 = 1:15
139/88 = 1.57
60 x 0.57 = 34.74
Thus, Alfred will not arrive in his city at 8 PM, but he will arrive at approximately 8:20 PM.

Answer:
Where is the paper?
Step-by-step explanation:
Here are summary statistics for randomly selected weights of newborn girls: n=250, x_=32.9 hg, s= 6.9 hg. Construct a confidence interval estimate of the mean. Use a 95% confidence level. Are these results very different from the confidence interval 31.9 hg < μ < 34.5 hg with only 19 sample values, x_=33.2 hg, and s=2.6hg? What is the confidence interval for the population mean μ?
Answer:
a) ( 31.92 < μ < 33.88 )
The confidence interval is not very different from the confidence interval given in the question
b) ( 31.74 , 34.66 )
Step-by-step explanation:
n = 250
x ( mean ) = 32.9
std = 6.9
95% confidence interval
df = n - 1 = 250 - 1 = 249
a) construct confidence interval estimate
calculate for the margin of error
= [tex]t_{0.05/2} ,_{250-1} ( \frac{s}{\sqrt{n} } )[/tex] ( using excel function: T.INV.2T(0.025,249) )
= 2.255 ( 6.9 / 15.81 )
= 0.98
Hence the confidence interval for the population
= ( x - 0.98 < μ < x + 0.98 )
= ( 31.92 < μ < 33.88 )
The confidence interval is not very different from the confidence interval given in the question
b) when n = 19
x = 33.2 and std = 2.6
margin of error = [tex]t_{0.05/2} ,_{19-1} ( \frac{s}{\sqrt{n} } )[/tex] = 2.45 * ( 2.6 / 4.36 ) = 1.46
confidence interval
= ( 33.2 - 1.46 , 33.2 + 1.46 )
= ( 31.74 , 34.66 )
Need help ASAP! Thanks
Answer:
A = 1, B = 1
Step-by-step explanation:
From the question
(2x+1)/(x²+x) = A/x + B/(x+1)
(2x+1)/(x²+x) = [A(x+1)+(Bx)]/(x²+x)
Equation the numerator
2x+1 ≡ A(x+1) +Bx
2x+1 ≡ Ax+A+Bx
From the above,
A = 1.
And,
2x = Ax+Bx................ Equation 1
A+B = 2
Substitute the value of A into Equation 1
1+B = 2
B = 2-1
B = 1
In a sewage treatment plant, a large concrete tank initially contains 440,000 liters of liquid and 10,000 kg of fine suspended solids. To flush this material out of the tank, water is pumped into the vessel at a rate of 40,000 l/h. Liquid containing solids leaves at the same rate. Estimate the concentration of suspended solids in the tank at the end of 4 h. You can assume that the initial concentration of solids in the tank
Answer:
[tex]Concentration = 8.26kg/m^3[/tex]
Step-by-step explanation:
Given
[tex]V = 440000L[/tex] --- volume of tank
[tex]m = 10,000 kg[/tex] --- solid mass
[tex]r = 40000L/hr[/tex] --- outflow rate
Required
Determine the concentration at the end of 4 hours
First, calculate the amount of liquid that has been replaced at the end of the 4 hours.
[tex]Amount = r * Time[/tex]
[tex]Amount = 40000L/hr * 4hr[/tex]
[tex]Amount = 40000L * 4[/tex]
[tex]Amount = 160000L[/tex]
This implies that, over the 4 hours; The tank has 160000 liters of liquid out of 440000 liters were replaced
Calculate the ratio of the liquid replaced.
[tex]Ratio = \frac{Amount}{Volume}[/tex]
[tex]Ratio = \frac{160000L}{440000L}[/tex]
[tex]Ratio = \frac{16}{44}[/tex]
[tex]Ratio = \frac{4}{11}[/tex]
Next, calculate the amount of solid left.
[tex]Amount (Solid)= Ratio * m[/tex]
[tex]Amount (Solid)= \frac{4}{11} * 10000kg[/tex]
[tex]Amount (Solid)= \frac{40000}{11}kg[/tex]
[tex]Amount (Solid)= 3636kg[/tex]
Lastly, the concentration is calculated as:
[tex]Concentration = \frac{Amount (Solid)}{Volume}[/tex]
[tex]Concentration = \frac{3636kg}{440000L}[/tex]
Convert L to cubic meters
[tex]Concentration = \frac{3636kg}{440000* 0.001m^3}[/tex]
[tex]Concentration = \frac{3636kg}{440m^3}[/tex]
[tex]Concentration = 8.26kg/m^3[/tex]

View the work below from a student last year. What was their mistake? Be detailed in their response.
-3(x + 4) = 2x - 5
-3x + 4 = 2x - 5
4 = 5x - 5
9 = 5x
1.8 = x
Answer:
x = -1.4
Step-by-step explanation:
-3(x + 4) = 2x - 5
-3x + (-3*4) = 2x - 5
The mistake was in the above equation where -3 should be multiplied with 4.
-3x -12 = 2x -5
5 -12 = 2x+3x
-7 = 5x
x = -7/5 = - 1.4

The function y=e−3x is vertically stretched by a factor of 4, reflected across the y-axis, and then shifted up 5 units, find the resulting function.
y=1/4e^3x-5
After a whole year this hasn't been answered
The resulting function of y=e^(−3x), when vertically stretched by a factor of 4, reflected across the y-axis, and then shifted up 5 units is y=[4e^(−3x)] + 5.
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs) etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units, y=f(x+c) (same output, but c units earlier)Right shift by c units, y=f(x-c)(same output, but c units late)Vertical shift
Up by d units: Down by d units: y = f(x) - dStretching:
Vertical stretch by a factor k: [tex]y = k \times f(x)[/tex]Horizontal stretch by a factor k: [tex]y = f(\dfrac{x}{k})[/tex]Given the function [tex]y=e^{-3x}[/tex] is vertically stretched by a factor of 4. Therefore, the function will be written as,
[tex]y = 4 \times e^{-3x}[/tex]
Now, the function is shifted up by 5 units, therefore, the function will become,
[tex]y = (4e^{-3x})+5[/tex]
Hence, the resulting function of y=e^(−3x) , when vertically stretched by a factor of 4, reflected across the y-axis, and then shifted up 5 units is y=[4e^(−3x)] + 5.

Answer:
(d) x-4
Step-by-step explanation:
If we assume your answer choices are ...
(a) 5 -x = 5 -4 = 1
(b) 1/2x = 1/2(4) = 2
(c) x +1 = 4 +1 = 5

find the area of the composite figure
Answer:
6808 yds
Step-by-step explanation:
First find the area in black in total
190 x 48 = 9120
then find the area of the two squares
34 x 34 = 1156
1156 x 2 = the two square combined = 2312
subtract the total area in black with the area of the combined squares
9120 - 2312 = 6808
