A health specialist gathered the data in the table to see if pulse rates can be explained by exercise,smoking,and age.For exercise,he assigns 1 for yes,2 for no.For smoking,he assigns 1 for yes,2 for no.
A)Pulse = 58.04 + 10.57 Exercise - 3.77 Smoke + 0.47 Age
B)Pulse = 24.1 + 8.15 Exercise + 6.33 Smoke + 0.83 Age
C)Pulse = 37.3 + 9.24 Exercise + 1.15 Smoke + 1.2 Age
D)Pulse = 58.04 + 10.57 Exercise + 3.77 Smoke + 0.47 Age
E)Pulse = 37.3 + 9.4 Exercise + 1.6 Smoke + 1.2 Age
