Test the claim that the mean GPA of night students is
significantly different than 2.4 at the 0.2 significance
level.
The null and alternative hypothesis would be:
О Но:р — 0.6
H1:p + 0.6
Ο H0: μ 2.4
H1:µ + 2.4
Но: р — 0.6
H1:p < 0.6
Ho : µ = 2.4
H1:µ < 2.4
Но: р — 0.6
H1:p > 0.6
О Но: д 3 2.4
H1: µ > 2.4
Based on a sample of 40 people, the sample mean GPA
was 2.37 with a standard deviation of 0.05
The test statistic is
(to 3 decimals)
The positive critical value is
(to 3 decimals)
Based on this we
reject the null hypothesis
O fail to reject the null hypothesis
