Test the claim that the mean GPA of night students is largerthan 2.1 at the .025 significance level.The null and alternative hypothesis would be:
H0:μ=2.1H0:μ=2.1H1:μ>2.1H1:μ>2.1
H0:p=0.525H0:p=0.525H1:p>0.525H1:p>0.525
H0:p=0.525H0:p=0.525H1:p≠0.525H1:p≠0.525
H0:μ=2.1H0:μ=2.1H1:μ<2.1H1:μ<2.1
H0:μ=2.1H0:μ=2.1H1:μ≠2.1H1:μ≠2.1
H0:p=0.525H0:p=0.525H1:p<0.525H1:p<0.525
The test is:
left-tailed
right-tailed
two-tailed
Based on a sample of 20 people, the sample mean GPA was 2.15 with astandard deviation of 0.05The test statistic is: (to 2 decimals)The critical value is: (to 2 decimals)Based on this we:
