Test the claim that the mean GPA of night students is larger than the mean GPA of day students at the 0.025 significance level. The null and alternative hypothesis would be:

• H0:pNpD H1:pN
• H0:pN=pD H1:pNpD
• H0:ND H1:N>D
• H0:ND H1:N
• H0:N=D H1:ND
• H0:pNpD H1:pN>pD

Correct The test is:

• left-tailed
• right-tailed
• two-tailed

Correct The sample consisted of 35 night students, with a sample mean GPA of 2.57 and a standard deviation of 0.03, and 35 day students, with a sample mean GPA of 2.56 and 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
• Fail to reject the null hypothesis
