Test the claim that the mean GPA of night students is significantly different than 2.2 at the U.02 significance level. The null and alternative hypothesis would be: Ho:µ = 2.2 H1:µ > 2.2 Ho: µ = 2.2 H1 : µ + 2.2 Ho:p = 0.55 H1:p + 0.55 Ho:p = 0.55 H1:p < 0.55 || Ho: µ = 2.2 Η :μ < 2.2 Ho:p = 0.55 H1:p > 0.55 Based on a sample of 40 people, the sample mean GPA was 2.21 with a standard deviation of 0.04 The test statistic is The positive critical value is Based on this we reject the null hypothesis fail to reject the null hypothesis Stickies
