     A   researcher collects data for relationship between daily exercise an   individual gets and the body fat % of individual. The researcher thanks that   exercise decreases % body fat. The following scores are recorded. The   regression equation for this data with the exercise as predictor and percent   body fat as outcome is Y = -0.476 x + 33.272 Individual 1 2 3 4 5 Exercise   (mins) 10 18 26 33 44 % body fat 30 25 18 17 14 Conduct Null hypothesis   significance test to determine whether exercise is correlated with percent   body fat. Remember to describe relationship between these variables.   Calculate and interpret the coefficient of determination for this data. If a   person exercises for 20 mins daily what would his or her predicted body fat%   be?
