You want to estimate the mean weight of quarters in circulation. A sample of 50 quarters has a mean weight of 5.625 grams and a standard deviation of 0.056 gram. Use a single value to estimate the mean weight of all quarters. Also, find the 95% confidence interval for the average weight of all quarters. grams. The estimate for the mean weight of all quarters is (Round to three decimal places as needed.) Find the 95% confidence interval for the mean weight of all quarters. grams<μ< grams (Round to three decimal places as needed.)
