A local health clinic surveys 50 patients about their water drinking habits. It found the data is normally distributed with a mean of 62 ounces and a standard deviation of 5.2. Estimate how much water, to the nearest hundredth of an ounce, do all of the clinic's patients drink each day, using a 95% confidence interval. (Recall the following z-scores for each level of confidence: 90% = 1.645, 95% = 1.960, and 99% = 2.575.)
