2. The following data represent the Statistics grade and intelligence test administered by the university guidance office. Intelligence test Student score (x) 56 54 55 1 2 3 4 5 6 7 8 9 10 65 70 70 59 62 66 65 Statistics Grade (y) 86 83 84 92 96 95 85 85 89 87 Compute the coefficient of correlation. Test whether the correlation between Intelligence Test Score and Statistics Grade is significant or not. Construct the scatter diagram. Find the estimate of the regression line. The Guidance Office would like to determine whether the Intelligence Test Score is a predictor of Statistics Grade. Test an appropriate hypothesis at significance level of 0.05. Compute the R squared. Interpret the results.
