Under the Wald test, the coefficients of which variables are statistically significant at the 0.1 alpha level? Select ALL correct answers.

For logistic regression, if one or more model assumptions do not hold (i.e. no goodness of fit), the predicting variables have no predictive power.

Question 2: Bike Data – Full Model (2a) 2 pts – Using bike_data_train, fit a poisson regression model with bikes as the response variable and all other variables as predicting variables. Include an intercept. Call it model1. Display the summary table for the model.  (2b) 2 pts – Provide a meaningful interpretation of the estimated regression coefficient for precipitation for model1. (2c) 3 pts – Perform a test for the overall regression on model1. Is model1 significant overall using an alpha of 0.05? Why/Why not?
