As part of a class project at a large university, Mary selected a random sample of 20 students in

her major field of study. All students in the sample were asked to report their number of hours

spent studying for the final exam and their score on the final exam. A regression analysis on the

data produced the following partial computer output.

a.) Mary would like to see if a relationship exists between studying and score on the test. Write

out your Ho and Ha and identify the variable of interest

b.) Let alpha = 0.10. What is the t score and p value? What is your conclusion and reason?
