Q6 The following scatter plot was made from a random sample of 500 adult males. The x-axis is height in inches. The y-axis is weight in pounds. The equation of best fit line and the correlation coefficient (r) is also given. 61 63 65 67 69 71 73 75 77 Height (inches) 140 160 180 200 220 240 Weight (lbs) y = 5.815x + -213.594 r = 0.85 Height vs. Weight for 500 alult males (a) Is it true that the tallest of the 500 men also weighs the most? (b) Use the equation of the line of best fit to predict the weight of a man who is 72 inches tall. (c) Would it be appropriate to use this equation to predict the weight of a man who is 6 foot 6 inches tall? Why or why not?

A pediatrician wants to determine the relation that may exist between a child's height and head circumference. She randomly selects eleven 3-year-old children from her practice and measures their heights and head circumference. According to the data, the linear correlation coefficient between the height and head circumference of a child is 0.918. Compute the coefficient of determination, R².
