It is expected that students who consistently perform well in major tests, quizzes, assignments and seatworks in the classroom also perform well in standardized achievement test. A teacher decided to examine this hypothesis. At the end of the academic year, she randomly selected 10 students from her class. She computes a correlation between the student's achievement test scores and the overall GPA for each student computed over the entire year. The data for the 10 students from her class are provided below. a. Compute the correlation coefficient. b. Interpret the result in A. c. Determine the regression equation.
