Test the claim that the mean GPA of night students is smaller than 2.4 at the .05 significance level.
The null and alternative hypothesis would be:
O Ho :p
Но: р — 0.6
H1:p < 0.6
Но: и — 2.4
H1:µ # 2.4
Ο Η: μ=2.4
Ні:и < 2.4
O Ho:p = 0.6
H1:p > 0.6
O Ho:P
H1:p + 0.6
O Ho : µ = 2.4
H1: µ > 2.4
Based on a sample of 45 people, the sample mean GPA was 2.39 with a standard deviation of 0.05
The test statistic is
(to 3 decimals)
The critical value is
(to 3 decimals)
Based on this we
O fail to reject the null hypothesis
reject the null hypothesis
