Excel File is here ( BodyFat (1).xls (https://canvas.ewu.edu/courses/1703706/files/114144174?wrap=1) (https://canvas.ewu.edu/courses/1703706/files/114144174/download?download_frd=1) BODY FAT DATA (Please download here) (https://canvas.ewu.edu/courses/1703706/files/114144125/download?wrap=1) (https://canvas.ewu.edu/courses/1703706/files/114144125/download?download_frd=1) Take the Quiz Again

The BODYFAT dataset was developed using randomly selected patients who were treated by a particular sports injury rehabilitation group. The purpose was to determine if girth (in centimeters) could be used to predict body fat (as a percentage) and to estimate the percentage of body fat (with 99% confidence) of a person who has a girth of 150cm. Girth is easily and accurately evaluated with a tape measure. Body fat percentage is measured via hydrostatic weighing, but this is too expensive and impractical to be easily deployed in most physicians' offices. Please conduct this analysis using a 1% significance level. 5 / 5 pts Question 1 What is the response variable for this analysis? Row number Girth Fat% 5 / 5 pts Question 2 What is the explanatory variable for this analysis? Girth Row number Fat%

5 / 5 pts Question 3 What type of data set is being analyzed? Medical Time-series Cross-sectional 5 / 5 pts Question 4 What value of alpha (as a proportion and not as a percent) will be used for this analysis? 0.01 5 / 5 pts Question 5 Please check the boxes for the following assumptions that have been met: Sample is reasonably representative of the population Central limit theorem is applicable Sample is large enough to support the analysis Independent variable is measured without error Predictions will not be extrapolating

Answer 6: Answer 7: Answer 8: is not assume is should 5 / 5 pts Question 11 Actual body fat percentage typically deviates from the predicted value by _____ percentage points (correct to four decimal points) 5.0864 5 / 5 pts Question 12 Girth explains _____ % of the variability in body fat percentage (correct to one decimal place). 67.1 5 / 5 pts Question 13

Increasing girth by one centimeter will increase average body fat percentage by _____ percentage points (correct to four decimal places). 0.5905 5 / 5 pts Question 14 A person with a girth of zero (??) centimeters will, on average, have a body fat percentage of _____ (correct to three decimal places). -36.24 5 / 5 pts Question 15 What body fat percentage can a person with a girth of 150cm reasonable expect (correct to three decimal places)? 52.339 5 / 5 pts Question 16 What is the lower bound of the average percentage of body fat (with 95% confidence) for all people who have a girth of 150cm (correct to three decimal places)?

The explanatory power of this regression suggests that girth is is a moderate predictor of body fat percentage. The standard error of the regression suggests that girth [ Select ] estimate body fat percentage to within 1.5% as does hydrostatic weighing. The 95% prediction interval for a person with a girth of 150cm [ Select ] a width of just under 25 percentage points, suggesting that this model [ Select ] reasonably estimate usefully for an individual. is a moderate
