The test is:
left-tailed
two-tailed
right-tailed
The sample consisted of 25 night students, with a sample mean GPA of 2.83 and a standard deviation of 0.07, and 25 day students, with a sample mean GPA of 2.81 and a standard deviation of 0.03.
The test statistic is: (to 2 decimals)
The p-value is: (to 2 decimals)
Based on this we:
- Fail to reject the null hypothesis
- Reject the null hypothesis
