Multiple Choice
A research project was conducted to study the effect of smoking and weight upon resting pulse rate.The response variable is coded as 1 when the pulse rate is low and 0 when it high.Smoking is also coding as 1 when smoking and 0 when not smoking.Shown below is Minitab output from a logistic regression.

Log-Likelihood = -46.820
Test that all slopes are zero: G = 7.574,DF = 2,P-Value = 0.023
The log of the odds ratio or logit equation is:
A) log(S) =-1.19297+0.0250226 Weight-1.98717 Smokes
B) S=-1.98717+0.025226 Weight-1.19297 Smokes
