3). Suppose that a sampling frame lists all households in Tampa. Investigator would like to estimate the average amount spent on food per week. However, the sampling frame does not include information on household size, and it only lists the households from US Census data. We have information about household sizes in the region. Investigator selects n=1000 households using SRS and information is given below. Household composition Number of households nn Sample Sample mean Variance Family 2,158,869 500 $275 24000 Non-family, > 1 person 177,873 50 $150 21000 Non-family, 1 person 795,271 450 $80 19000 Total 3,132,013 1000
