Records of drivers with a major medical condition (diabetes, heart condition, or epilepsy) and also a group of drivers with no known health conditions were retrieved from a motor vehicle department. Drivers in each group were classified according to their driving record in the last year.

Let pD, pH, pE, and pc denote the population proportions of drivers having one or more traffic violations in the last year for the four groups "diabetes," "heart condition," "epilepsy," and "control," respectively.
(a) Test H0: pD = pC versus H1: pD > pC at α = .10.
(b) Is there strong evidence that pE is higher than pC? Answer by calculating the P-value.
