A study was conducted to detemine whether a 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 verbal scores and final grades for 10 students are shown in the table below. Student Verbal Score z Final Grade y 1 42 84 36 71 75 63 51 45 35 41 2 3 4 5 6 7 8 9 10 A 32 73 34 57 66 51 35 26 33 Find the least squares line. (Give each answer to at least three decimal places.) Should the regression be used to predict the final grade of a student with a verbal score of 100? Enter "yes" or "no". answer:
