2. Wage earners in a large firm are stratified into management and clerical classes, the first have 300 employees and the second 500 employees. To assess attitude on sick-leave policy, independent random samples of 100 workers were selected from each of the classes. After the sample data were collected, the responses were divided according to gender. In the table of results, a = Number who like the policy; b = Number who dislike the policy; and c = Number who have no opinion. Male Female Total Management N₁ = 300 a = 60 b=15 c=5 a = 10 b=7 c=3 n₁ =100 Clerical N₂ = 500 a = 24 b=4 c=2 a = 42 b=20 c=8 n₂ = 100 Total N = 800 100 90 n= 200 Find the estimate and the associated variance estimate for the population parameters in each of the following situation: a. Proportion of managers who like the policy. b. Proportion of clerical workers who like the policy. c. Proportion of wage earners who like the policy.
