ANSWER PARTSD,E,F 1. A study of the relation between the waistline and percent body fat inmen yielded the data shown (waistline measurement in inches).waistline (x) 34.7 46.5 32.8 41.3 29.8 39.3 35.7 29.0percent fat (y) 21.8 33.6 13.4 27.1 13.7 30.2 18.5 11.2x = 36.1375 y = 21.1875 SSxx = 248.53875 SSay = 332.67375 SSyy = 494.30875(a) Find the proportion of the variability in percent body fat that isaccounted for by the size of the waistline. Explain fully.(b) Find the regression line for predicting y from x.(c) Construct a 95% confidence interval for the average percent body fatof all men whose waistline size is 34.0 inches.(d) test HO: Beta1 is 0 vs. Ha : Beta1 is not 0, compute the appropriatetest statistic and p-value, then make your decision at a = 0.05.(e) Construct a 90% confidence interval for beta1.(f) Compute a 90% confidence interval for the average percent fat whenwaistline is 35.
