larger than the mean GPA of Coastline students at the 0.005
significance level.
The null and alternative hypothesis would be:
H0:μO≤μCH0:μO≤μC
H1:μO>μCH1:μO>μC
H0:pO=pCH0:pO=pC
H1:pO≠pCH1:pO≠pC

H1:μO<μCH1:μO<μC
H0:pO≤pCH0:pO≤pC
H1:pO>pCH1:pO>pC
The test is:
right-tailed
left-tailed
two-tailed
The sample consisted of 40 Orange Coast students, with a sample
mean GPA of 2.11 and a standard deviation of 0.05, and 40 Coastline
students, with a sample mean GPA of 2.09 and a standard deviation
of 0.07.
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
