1. A local health clinic sent fliers to its clients to encourage everyone to get a flu shot. In a pilot follow-up study, 159 clients were randomly selected and asked whether or not they actually received a flu shot. A client who did receive a flu shot was coded Y=1 and a client who did not was coded Y=0. In addition, data were collected on their age (X1), on their health awareness (X2, an index where higher values indicate greater awareness), and their gender (X3 = 1 for males, X3 = 0 for females).

A researcher suggests to you that it will be easier to interpret results from this study if you center both the variables "age" and "awareness" at 60. You agree to fit the first-order logit model
