If our statistical analysis shows that the significance level is below the cut-off value we … WebThe conclusion of the following hypothesis is whether high school GPA is a good predictor of first-year college GPA. With an alpha of 0.05 and a p-value of 0.1064, we fail to reject the null and state that we have insufficient evidence to support that the true slope between high school GPA and first-year college GPA is not equal to zero.
