Question 2

Partially correct

Mark 1.50 out of 2.00

v1 (latest)

A college bookstore must order books two months before each semester starts. They believe that the number of books that will ultimately be
sold for any particular course is related to the number of students registered for the course when the books are ordered. They would like to
develop a linear regression equation to help plan how many books to order. From past records, the bookstore obtains the number of students
registered, X, and the number of books actually sold for a course, Y, for 9 different semesters. These data are below. Find a regression
equation between students and books ( 1 Mark). Then use the regression equation to find the number of books for 20 students (1 Mark) and
40 students (1 Mark).
