A fitness rating was obtained for 9 randomly selected adult women. Each person was also asked her age, weight, and the number of hours she spent exercising each week. The results are shown below. Age 39 27 41 48 56 59 22 64 35 Weight 140 129 137 125 162 152 118 142 126 Hours of exercise per week 2 6 4 9 0 3 11 3 4 Fitness rating 72 88 63 84 47 52 90 31 64 Identify the multiple regression equation that expresses fitness in terms of age, weight, and hours of exercise per week.
A)^F = 36.07 - 1.02A + 0.429W + 3.30E
B)^F = 52.46 - 2.14A + 1.39W + 2.48E
C)^F = 23.79 - 1.36A + 0.241W + 1.43E
D)^F = -45.12 + 0.918A + 0.461W + 3.30E

Question

Quizplus · Accepted Answer

The correct multiple regression equation is chosen based on the statistical analysis of the given data, which involves calculating coefficients that best fit the relationship between the dependent variable (fitness rating) and the independent variables (age, weight, hours of exercise per week). Option A is identified as the correct equation based on this analysis.
