As of 2012, the proportion of students who use a MacBook as their primary computer is 0.31. You believe that at your university the proportion is actually different from 0.31. The hypotheses for this test are Null Hypothesis: p = 0.31, Alternative Hypothesis: p # 0.31. If you randomly select 24 students in a sample and 12 of them use a MacBook as their primary computer, what is your test statistic and p-value?

Question
As of 2012, the proportion of students who use a MacBook as their primary computer is 0.31. You believe that at your university the proportion is actually different from 0.31. The hypotheses for this test are Null Hypothesis: p = 0.31, Alternative Hypothesis: p + 0.31. If you randomly select 24 students in a sample and 12 of them use a MacBook as their primary computer, what is your test statistic and p-value? 1) Test Statistic: 2.013, P-Value: 0.978 2) Test Statistic: 2.013, P-Value: 0.956 3) Test Statistic: 2.013, P-Value: 0.044 4) Test Statistic: 2.013, P-Value: 0.022 5) Test Statistic: -2.013, P-Value: 0.044
