Step-by-step explanation:
Let p be the true proportion of water specimens that contain detectable levels of lead. The point estimate for p is . The estimated standard deviation is given by . Because we have a large sample, the 90% confidence interval for p is given by where is the value that satisfies that above this and under the standard normal density there is an area of 0.05. So, the confidence interval is , i.e., (0.4958, 0.7422).
