H1:μ>3.5H1:μ>3.5
H1:μ>3.5H1:μ>3.5
H0:p≤0.875H0:p≤0.875
H1:p>0.875H1:p>0.875
H1:p>0.875H1:p>0.875
H0:μ≥3.5H0:μ≥3.5
H1:μ<3.5H1:μ<3.5
H1:μ<3.5H1:μ<3.5
H0:p≥0.875H0:p≥0.875
H1:p<0.875H1:p<0.875
H1:p<0.875H1:p<0.875
H0:p=0.875H0:p=0.875
H1:p≠0.875H1:p≠0.875
H1:p≠0.875H1:p≠0.875
H0:μ=3.5H0:μ=3.5
H1:μ≠3.5H1:μ≠3.5
H1:μ≠3.5H1:μ≠3.5
The test is:
two-tailed
left-tailed
right-tailed
Based on a sample of 35 people, the sample mean GPA was 3.51 with a standard deviation of 0.08
The test statistic is: (to 2 decimals)
The p-value is: (to 2 decimals)
Based on this we:
- Reject the null hypothesis
- Fail to reject the null hypothesis
