Test the claim that the mean GPA of Orange Coast students is smaller than the mean GPA of Coastline students at the 0.01 significance level. The null and alternative hypothesis would be: Ho:po pc H:μο < με Hy:po #pc pc The test is: two-tailed right-tailed left-tailed O O The test statistic is: The p-value is: The sample consisted of 80 Orange Coast students, with a sample mean GPA of 2.21 and a standard deviation of 0.04, and 80 Coastline students, with a sample mean GPA of 2.22 and a standard deviation of 0.06.
