A researcher wished to compare the average amount of time spent in extracurricular activities by high school students in a subur

ban school district with that of high schoolers in a school district of a large city. The researcher obtained an SRS of 60 high school students in a large suburban school district and found the mean time spent in extracurricular activities per week to be x1 = 6 hours, with a standard deviation s1 = 3 hours. The researcher also obtained an independent SRS of 40 high school students in a large city school district and found the mean time spent in extracurricular activities per week to be x2 = 4 hours, with a standard deviation s2 = 2 hours. Let µ1 and µ2 represent the mean amount of time spent in extracurricular activities per week by the populations of all high school students in the suburban and city school districts, respectively. Assume the two-sample t-procedures are safe to use.Suppose the researcher had wished to test the hypothesesH0: µ1 = µ2, Ha: µ1 ? µ2.
The P-value for the test is
A. 0.01.B. 0.05.C. 0.001.D. below 0.000123.

Inventory was taken on Day 1, Day 2, Day 5, Day 6, and Day 7. Norris wants to know roughly what the inventory was on Day 3.
Dvinal [7]

He should evaluate the function f(x)=−1/3 x+4 for x=3  , Option D is the correct answer.

<h3>What in Interpolation ?</h3>

Interpolation is when the line of best fit is used to determine the value of a point that is within the range of plotted points.

It is given to find the value at Day 3 which lies in the range of the points used for plotting

The line for best fit is

f(x) = (-1/3)x +4

At x = 3

f(3) = (-1/3) * 3 +4

f(3) = -1+4 = 3

Therefore He should evaluate the function f(x)=−1/3 x+4 for x=3

Option D is the correct answer.

In a New York Times/CBS News Poll, respondents were asked if it should be legal or illegal to send a text message while driving.
AnnZ [28]

Answer: \dfrac2{201}

Step-by-step explanation:

Number of persons said it is legal to text while driving = 8

Number of persons said it is illegal to text while driving = 804

Total persons sampled = 804+8 = 812

Since probability =\dfrac{\text{favorable outcomes}}{\text{Total outcomes}}

The probability of randomly selecting someone who believes it should be legal to text while driving = \dfrac{8}{804}=\dfrac2{201}

Required probability = \dfrac2{201}
