Test the daim that the mean GPA of night students is smaller than the mean GPA of day students at the 0.05
significance level.
The null and alternative hypothesis would be:
Ho:PN = PD Ho:HN > Hp Ho:PN > PD Ho:HN = HD Ho:HN < Hp Ho:PN < PD
Ha:PN + PD H.:µN < HD Ha:PN < Pp Ha:µN + HD Ha:µN > µp Ha:PN > PD
The test is:
right-tailed left-tailed two-tailed
The sample consisted of 16 night students, with a sample mean GPA of 3.28 and a standard deviation of 0.02,
and 14 day students, with a sample mean GPA of 3.3 and a standard deviation of 0.03.
test statistic =
[three decimal accuracy]
p-value =
[three decimal accuracy]
Based on this we:
O Fail to reject the null hypothesis
O Reject the null hypothesis
