Note: Use MS Excel for this problem! The following data were collected on the height (inches) and weight (pounds) of 6 students. Height (Inches), x Weight (Pounds), y 61 117 64 122 67 135 67 145 69 153 69 188 a) Calculate the correlation coefficient, r: (3 decimal places) b) Write down the regression model to predict weight based on height: y = (2 decimal places) . x + (two decimal places). c) What percent of the total variation in weight has been explained by height? % (percent to one decimal place) d) What is the predicted value of weight if height is 63.01 inches (one decimal place)
