Test the claim that the mean GPA of Orange Coast students is larger than the mean GPA of
Coastline students at the 0.01 significance level.
The null and alternative hypothesis would be:
=
Ho: Po
με Ho:μο < με Ho:po >pc
H:μο # με H:μο > με Hi:po < pc
The test is:
right-tailed left-tailed two-tailed of
The sample consisted of 40 Orange Coast students, with a sample mean GPA of 2.11 and a
standard deviation of 0.08, and 40 Coastline students, with a sample mean GPA of 2.06 and a
standard deviation of 0.03.
The test statistic is: 3.68
The p-value is: 0
Based on this we:
Ho:po = pc Ho:po Spc Ho:μο 2 με
Hi:po + pc Hi:po > pc Hı:mo < με
Reject the null hypothesis
