Suppose that a survey is being planned for purposes of estimating the average number of hours spent exercising daily by adults (18 years of age or older) living in a certain area at Batu Pahat. Suppose this list consists o: five households and the information of hours spent for exercising are shown in Table Q1(d). (d) Table Q1(d) : Number Of Hours Spent For Exercising By Adults Number of Hours Spent for Exercising by All Adults Household 1 2 2 9 3 14 4 40 12 Compute and list down all possible samples if sample of two households are selected. (i) (ii) For the first sampling plan, select all possible sample as listed in Q1(d)(i) and calculate the expected value of mean and variance of the estimated mean number of hours spent for exercising. (iii) For the second sampling plan which consist of household (1 and 2), (1 and 3), (1 and 4), (1 and 5), and (2 and 3), calculate the expected value of mean and variance of the estimated mean number of hours spent for exercising.

Question
Suppose that a survey is being planned for purposes of estimating the average number of hours spent exercising daily by adults (18 years of age or older) living in a certain area at Batu Pahat. Suppose this list consists of five households and the information of hours spent for exercising are shown in Table Q1(d). (d) Table Q1(d) : Number Of Hours Spent For Exercising By Adults Number of Hours Spent for Exercising by Household All Adults 1 2 9. 3 14 4 40 5 12 Compute and list down all possible samples if sample of two households are selected. (i) (ii) For the first sampling plan, select all possible sample as listed in Q1(d)(i) and calculate the expected value of mean and variance of the estimated mean number of hours spent for exercising. (ii) For the second sampling plan which consist of household (1 and 2), (1 and 3), (1 and 4), (1 and 5), and (2 and 3), calculate the expected value of mean and variance of the estimated mean number of hours spent for exercising. (iv) Which sampling plan is bias? Explain your answer. 2.
