Exercise 7

Use the data in ATTEND.RAW for this exercise.

(i) Obtain the minimum, maximum, and average values for the variables atndrte, priGPA, and ACT.

(ii) Estimate the model

atndrte = ?0 + ?1priGPA + ?2 ACT + u,

and write the results in equation form. Interpret the intercept. Does it have a useful meaning?

(iii) Discuss the estimated slope coefficients. Are there any surprises?

(iv) What is the predicted atndrte if priGPA = 3.65 and ACT = 20? What do you make of this result? Are there any students in the sample with these values of the explanatory variables?

(v) If Student A has priGPA = 3.1 and ACT = 21 and Student B has priGPA = 2.1 and ACT = 26, what is the predicted difference in their attendance rates?
