The hypotheses for this test are Null Hypothesis: p = 0.32, Alternative Hypothesis: p ≠ 0.32. If you randomly select 26 students in a sample and 9 of them use a MacBook as their primary computer, what is your test statistic and p-value?

Question 11 options:

1)

Test Statistic: 0.286, P-Value: 0.612

2)

Test Statistic: 0.286, P-Value: 0.388

3)

Test Statistic: -0.286, P-Value: 0.775
