The test is: two-tailed right-tailed left-tailed
Based on a sample of 38 people, the sample mean GPA was 3.08 with a standard deviation of 0.12
The p-value is: __?__(to 3 decimals)
The positive significance level is: __?__(to 2 decimals)
Based on this we:
- a) Fail to reject the null hypothesis
- b) Reject the null hypothesis
