H0:2H0:2 H1:>2H1:>2 H0:p0.5H0:p0.5 H1:p<0.5H1:p<0.5 H0:p=0.5H0:p=0.5 H1:p0.5H1:p0.5 H0:=2H0:=2 H1:2H1:2 H0:p0.5H0:p0.5 H1:p>0.5H1:p>0.5 H0:2H0:2 H1:<2H1:<2 The test is:

two-tailed right-tailed left-tailed Based on a sample of 45 people, the sample mean GPA was 1.99 with a standard deviation of 0.02 The test statistic is: (to 2 decimals) The p-value is: (to 2 decimals) Based on this we:

• Reject the null hypothesis
