Test the claim that the mean GPA of night students is smallerthan 3.1 at the .05 significance level.The null and alternative hypothesis would be:
H0:μ=3.1H0:μ=3.1H1:μ<3.1H1:μ<3.1
H0:p=0.775H0:p=0.775H1:p≠0.775H1:p≠0.775
H0:μ=3.1H0:μ=3.1H1:μ≠3.1H1:μ≠3.1
H0:μ=3.1H0:μ=3.1H1:μ>3.1H1:μ>3.1
H0:p=0.775H0:p=0.775H1:p<0.775H1:p<0.775
H0:p=0.775H0:p=0.775H1:p>0.775H1:p>0.775
The test is:
right-tailed
left-tailed
two-tailed
Based on a sample of 35 people, the sample mean GPA was 3.07 with astandard deviation of 0.08The test statistic is: (to 2 decimals)The critical value is: (to 2 decimals)Based on this we:
