The maximum amount an athlete can bench press is often used as a measurement of their overall strength. But women tend to carry a larger percentage of their muscles in their legs than men do. How are x-maximum bench press (BP) and y maximum leg press related fo「female high school athletes? A regression model was fit to the x and y variables above; the results are as follows: Predictor Coefficient SE Coef T P Constant 173.988 41.75 4.170.000 BP 2.2158 0.5155 4.300.000 (a) Sally's maximum bench press is 80 pounds. What does this model predict for her maximum leg press? 351.252 (b) Match the following intervals to their appropriate interpretations. (This question is easier to read on a wider screen.) My model predicts that 95% of girls who can bench press 80 pounds have a max leg press between 247.70 and 454.80 pounds. I am 95% sure the average max leg press for girls who can bench press 80 pounds is between 337.65 and 364.84 pounds I am 95% sure when a girl bench presses one more pound, her max leg press increases by between 115 and 3.28 pounds, on average A 95% confidence interval for the slope. A 95% prediction interval for max leg press when x = 80. A 95% confidence interval for the mean bench press. A 95% confidence interval for the mean max leg press when x-80.
