economic survey

In the survey in Exercise 8.10, the number of households in the city is not known. Estimate the total amount spent on utilities for all households in the city and place a bound on the error of estimation.

Exercise 8.10

An economic survey is designed to estimate the average amount spent on utilities for households in a city. Because no list of households is available, cluster sampling is used, with divisions (wards) forming the clusters. A simple random sample of 20 wards is selected from the 60 wards of the city. Interviewers then obtain the cost of utilities from each household within the sampled wards; the total costs are shown in the accompanying table. Estimate the average amount a household in the city spends on utilities and place a bound on the error of estimation.
