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 pvalue?

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
Pvalue = P(Z > 0.631) = 0.264
1) 
Test Statistic: 0.631, PValue: 0.264 
12)
Claim: The average stock price for sitdown restaurants different from the average stock price for fast food restaurants.
