Solve the given problem: 1. In an attempt to assess the effect of the length of time spent in using social media to the academic performance of the student, a survey was conducted to ten randomly selected students to determine the number of minutes per week using social media and their scores in a department examination in mathematic which consists of a 50-item test. The data are as follows: Minutes spent using social media per week (x) Score in the department exam (y) 30 45 45 48 60 42 120 40 180 38 200 43 240 20 300 29 320 35 400 15 a. Compute for the correlation coefficient r. b. Compute for the value of m and b. c. Form the regression equation
