1. The table below presents the test-firing results for 25 surface-to-air antiaircraft missiles at targets of varying speed. The result of each test is either a hit (y = 1) or a miss (y = 0).

a. Fit a logistic regression model to the response variable y. Use a simple linear regression model as the structure for the linear predictor.

b. Does the model deviance indicate that the logistic regression model from part a is adequate?

c. Provide an interpretation of the parameter ?₁in this model.

d. Expand the linear predictor to include a quadratic term in target speed. Is there any evidence that this quadratic term is required in the model?
