1. A simple random sample of 100 water meters within a community is monitored to estimate the average daily water consumption per household over a specified dry spell. The sample mean and sample variance are found to be 37 = 12.5 and $2 = 1252. Assume that there are N = 10,000 households within the community. (a) Estimate u, the true mean daily consumption. (b) Place a bound on the error of estimation with 95% confidence level. (c) Estimate the total number of gallons of water, 1', used daily during the dry spell and place a bound on the error of estimation with 95% confidence level
