Run
a logistic regression on each of the following data (urban and rural) sets
using a single predictor (IV) called High School GPA (HSgpa) to predict gun ownership (gun). Note that gun = 1 indicates that the person is a gun owner.
These data are

numbers.

out the logistic formula.
3.
Interpret
Beta as (a) the log odds, (b) an odds ratio (c) percent of change. Don't forget
to tell me if the coefficient is significant.

both the Wald and LR confidence intervals (in odds ratios). Are they similar?
Why or why not?
