This prоblem uses the dаtаset BоdyFаt, which gives the percent оf weight made up of body fat for 100 men as well as other variables such as Age, Weight (in pounds), Height (in inches), and circumference (in cm) measurements for the Neck, Chest, Abdomen, Ankle, Biceps, and Wrist. 6 pts The regression line for predicting body fat percent using neck circumference is Body fat = -47.9 + 1.75 (neck) a. What body fat percent does the line predict for a person with a neck circumference of 35 cm? Round your answer to two decimal places. ____________% What body fat percent does the line predict for a person with a neck circumference of 40 cm? Round your answer to one decimal place. ____________% b. One of the men in the study had a neck circumference of 38.7 cm and a body fat percent of 11.3. Find the residual for this man.Round your answer to three decimal places. Residual = ____________%
Mаjоr Leаgue Bаseball is split intо twо leagues, the National League (NL) and the American League (AL). The main difference between the two leagues is that pitchers take bats in the National League but not in the American League. Two of the variables in the BaseballHits dataset are the number of wins and the number of runs scored during the season. The dataset consists of values for each variable from all 30 MLB teams. From these data we calculate the regression line: 10 pts Wins = 34.85 + 0.070(runs) a. Which is the explanatory variable in this regression line? a. Wins b. Runs Answer: _______ b. Interpret the slope in context. a. The expected number of runs given one win. b. The expected number of wins given one run. c. The expected change in number of runs given one more win. d. The expected change in number of wins given one more run. Answer: ________ c. The San Francisco Giants won 88 games while scoring 665 runs in 2014. Predict the number of games won by San Francisco using the regression line. Round your answer to one decimal place. Wins = ___________ Calculate the residual. Round your answer to one decimal place. Residual = _____________ Were the Giants efficient at winning games with 665 runs? Choose the answer in accordance to (c) of the question statement Answer: _________(Yes or No)
