In a survey of South African drivers, 79% of women drivers and 85% of men drivers said that they exceeded the speed limit at least once in the past week. Suppose that these percentages are based on random samples of 600 women and 700 men drivers. Let P subscript 1 and P subscript 2 be the proportion of all women and men drivers, respectively. Using 98% confidence level. Determine the standard error: a) 0.021 b) 0.049 c) 0.790 d) 0.590 Determine the confidence interval of P1 - P2: a) (0.010;0.110) b) (-0.110; -0.010) c) (1.026; 1.126) d) (0.979; 0.879) Determine the point estimate of P1 - P2: a) 0.060 b) -0.060 c) 1.076 d) 0.929
