Question: Can a pretest on mathematics skills predict success in a statistics course? The 102 students in an introductory statistics class took a pretest at the beginning of the semester. The least-square regression line for predicting the score y on the final exam from the pretest score x was \(\hat{y}=10.5+0.73x\). The standard error of b₁ was 0.42.

Test the null hypothesis that there is no linear relationship between the pretest score and the score on the final exam, using an appropriate t-test.
