Question: Can a pretest on mathematics skills predict success in a statistics course? The 83 students in an introductory statistics class took a pretest at the beginning of the semester. The least-squares regression line for predicting the score y on
the final exam from the pretest score x was} = 9.7 + 0.76x. The standard error
of by was 0.44.
- Test the null hypothesis that there is no linear relationship between the pretest score and the score on the final exam against the two-sided alternative.
- Would you reject this null hypothesis versus the one-sided alternative that the slope is positive? Explain your answer.
