Estimate the logistic regression model to compute the probability and the odds when x₁ = 12 and x₂ = 8.

Note: Do not round intermediate calculations and round final answers to 2 decimal places.

What is the percentage change in the odds when x₁ increases by one unit, holding x₂ constant?

Note: Do not round intermediate calculations and round final answer to 2 decimal places.
