Check Your Understanding: Michael is a runner. He uses his Apple watch to keep track of his distance and the number of calories he burns
Check Your Understanding: Michael is a runner. He uses his Apple watch to keep track of his distance and the number of calories he burns for 20 runs. A scatterplot of y = calories burned and x = distance (in miles) shows a fairly strong positive linear relationship. The regression equation 9 = 20 + 160x models the data fairly well. a. Interpret the slope of the regression line. b. Does the value of the y intercept have meaning in this context? If so, interpret the y intercept. If not, explain why. c. Predict the number of calories Michael burns if he runs 5 miles. d. Calculate and interpret the residual if his Apple watch said that he burned 910 calories on a 5-mile run. e. Michael is thinking about signing up for his first marathon. So far, his longest run has only been 10 miles. Should he use the regression equation to predict how many calories he would burn if he runs a marathon (26.2 miles)? Explain. 17 + STATS MEDIC
