2.) The following data represent the Statistics grades for a random sample of 12 freshmen-nursing students of OLFU along with their IQ score. a.) Construct the scatter diagram. b.) Compute and interpret the sample correlation coefficient. c.) Test the null hypothesis that there is no significant relationship between the IQ score and the Statistics grade at 0.05 level of significance. Statistics Student IQ Score Grade 1 65 85 74 50 3 55 76 4 65 70 90 85 87 5 65 70 55 70 50 55 75 6 7 94 8 9 10 11 85 90 81 91 12 76 74 13 80 65 70 14 80 70 15
