Test the claim that the mean GPA of night students is smaller than 2.3 at the 0.025 significance level. The null and alternative hypothesis would be: H0:μ≤2.3 H1:μ>2.3 H0:p≤0.575 H1:p>0.575 H0:p=0.575 H1:p≠0.575 H0:μ=2.3 H1:μ≠2.3 H0:μ≥2.3 H1:μ<2.3 H0:p≥0.575 H1:p<0.575 The test is: left-tailed two-tailed right-tailed Based on a sample of 80 people, the sample mean GPA was 2.26 with a standard deviation of 0.04 The test statistic is: (to 2 decimals) The p-value is: (to 2 decimals) Based on this we: Fail to reject the null hypothesis Reject the null hypothesis
