The output below shows a further analysis of the dataset used in question 3. This time the variable BK has been included. It is a categorical variable that indicates whether or not the person owns a pet bird. Using the output below construct a 95% Wald Cl for the multiplicative effect of owning a pet bird on the odds of having lung cancer. Give the lower and upper limits of the CI to two decimal places. > library (Sleuth3) > case2002$LC case2002$BK fit summary (fit) Call : glm (formula = LC ~ YR + BK, family = binomial, data = case2002) Deviance Residuals: Min 10 Median 30 Max -1 . 6093 -0.8644 -0. 5283 0. 9479 2. 0937 Coefficients : Estimate Std.
