Q4_1 The age x and resting heart rate y were measured for ten men, with the results shown in the table. a) Compute the linear correlation coefficient for these sample data and interpret its meaning in the context of the problem. b) Compute the least squares regression line and plot. c) Estimate the average resting heart rate of all 40-year-old men. d) Estimate the average resting heart rate of all newborn baby boys. Comment on the validity of the estimate. e) Compute the coefficient of determination and interpret its value in the context of age and resting heart rate. In the age range of the data, does age seem to be a very important factor with regard to heart rate? Hint: - You should use tables "Critical Values of t" or "Cumulative Probability P(ZZ) in Q3 1. (or use "Probability Distribution Plot" in Minitab) - Consider that the area of which side of tail is cut off by z while calculating p-value. - You can prefer excel or Minitab in the calculations of Q4_1
