A study was conducted to determine whether the final grade of a
student in an introductory psychology course is linearly related to
his or her performance on the verbal ability test administered
before college entrance. The researchers hypothesized the linear
model y=β0+β1xy=β0+β1x, where xx is the score on the verbal ability
test and yy is the final grade in the psychology course. The verbal
scores and final grades for students are shown in the table
below.
