Write down the Poisson regression model equation relating the logarithm of the mean count of cigarettes smoked to the covariate location. Then write two separate equations for the model: one for each of the possible locations (location = 0 if the person is at home, and location = 1 if the person is at work). Set each of these two equations equal to the logarithm of the corresponding average that you found in Question 40. Solve the resulting system of two equations and two unknowns (β₀ and β₁) for estimates of the intercept and slope (b₀ and b₁).
