Test the claim that
the mean GPA of Orange Coast students is significantly different
than the mean GPA of Coastline students at the 0.05 significance
level.
The null and alternative hypothesis would be:
The test is: two-tailed, right-tailed, left-tailed?
The sample consisted of 60 Orange Coast students, with a sample
mean GPA of 3.38 and a standard deviation of 0.04, and 60 Coastline
students, with a sample mean GPA of 3.41 and a standard deviation
of 0.06.
The test statistic is: (to 2 decimals)
The p-value is: (to 2 decimals)
Based on this we: Fail to reject the null hypothesis or Reject the
null hypothesis?
