neighboring city

The economic survey in Exercise 8.10 is to be performed in a neighboring city of similar structure. The objective is to estimate the total amount spent on utilities by households in the city, with a bound of $5000 on the error of estimation. Use the data in Exercise 8.10 to find the appropriate number of clusters needed to achieve this bound.

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.
