- If every 13th item is systematically sampled to produce a sample size of 72 items, approximately how large is the population?(Use an excel file to show formulas used)(d) As part of a marketing program, a city block containing 4 households was selected and a sample of 3 households was sampled as follows. Jeremiah, the research assistant, identified the households and numbered each household from 1 to 4. He then want to list all combinations of the 4 households 2 at a time. These are: 1 and 2 1 and 3 1 and 4 2 and 3 2 and 4 3 and 4 Unfortunately, Jeremiah got this job because he was related to the Department Chairman, and he was very careless. He forgot the combina- tion 3 and 4. He chose a random number between 1 and 5 (it turned out to be 4) which corresponded to the combination 2 and 3. Thus households 2 and 3 were sampled. The variable of interest was out-of-pocket medical expenses incurred by the household (Table Q1 (d)). Table Q1 (d) : Out-Of-Pocket Medical Expenses Incurred by the Household Expenses ($) 345.00 Household 1 126.00 492.00 962.00 3 4 (ii) Based on Jeremiah's sampling procedure, what is the expected value of mean and variance of…
