significance level.
The null and alternative hypothesis would be:
Ho : | = 3.3
H₁ μ3.3
OH: @= 3.3
Η : μ > 3.3
Ho p =
0.825
H₁: p
0.825
Ho: p = 0.825
H₁: p < 0.825
Ho: p = 0.825
H₁: p > 0.825
OH: |=3.3
Η : μ < 3.3
Based on a sample of 40 people, the sample mean GPA was 3.25 with a standard deviation of 0.08
The test statistic is -39.528
The positive critical value is 2.426
Based on this we
○ fail to reject the null hypothesis
reject the null hypothesis
