3) It is known that high chemistry test scores are associated with above average intelligence test scores. The following data for chemistry and intelligence test scores for 6 students was collected. (a) Sketch the scatter plot and (b) Calculate correlation coeffi- cient and interpret. (To make your calculation easier, the mean scores for Intelligence and chemistry test scores are 60.0 and 82.8. respectively, and the sample standard deviation for Intelligence and chemistry scores are 7.75 and 6.37, respectively) Intelligence score: 65 50 55 65 55 70 Chemistry Score 85 74 76 90 85 87
