Question 11 (1 point)

As of 2012, the proportion of students who use a MacBook as their primary computer is 0.41. You believe that at your university the proportion is actually greater than 0.41. The hypotheses for this test are Null Hypothesis: p ≤ 0.41, Alternative Hypothesis: p > 0.41. If you randomly select 30 students in a sample and 14 of them use a MacBook as their primary computer, what is your test statistic and p-value?

Question 11 options:

 1) Test Statistic: 0.631, P-Value: 0.264
 2) Test Statistic: -0.631, P-Value: 0.264
 3) Test Statistic: -0.631, P-Value: 0.736
 4) Test Statistic: 0.631, P-Value: 0.528
 5) Test Statistic: 0.631, P-Value: 0.736

Question 12 (1 point)

Do sit down restaurant franchises and fast food franchises differ significantly in stock price? Specifically, is the average stock price for sit-down restaurants different from the average stock price for fast food restaurants? If sit down restaurants are considered group 1 and fast food restaurants are group 2, what are the hypotheses of this scenario?

Question 12 options:

 1) HO: μ1 = μ2 HA: μ1 ≠ μ2
 2) HO: μ1 ≠ μ2 HA: μ1 = μ2
 3) HO: μ1 ≥ μ2 HA: μ1 < μ2
 4) HO: μ1 ≤ μ2 HA: μ1 > μ2
 5) HO: μ1 > μ2 HA: μ1 ≤ μ2

11)

Claim: The proportion is actually greater than 0.41.

The null and alternative hypothesis is

H0: P 0.41

H1: P > 0.41

Sample size = n = 30

x = 14

Test statistic is

P-value = P(Z > 0.631) = 0.264

 1) Test Statistic: 0.631, P-Value: 0.264

12)

Claim: The average stock price for sit-down restaurants different from the average stock price for fast food restaurants.

 1) HO: μ1 = μ2 HA: μ1 ≠ μ2
