I. Analyze the data in Table, using logistic regression to analyze sets of 2 2 tables.

(a) Report the conditional odds ratios for each department and their 95% confidence intervals.

(c) If you delete the data for Department 1, do you think a common odds ratio is reasonable? If so, report an estimate for the common odds ratio using computer output and report a 90% confidence interval for this quantity.
