You want to estimate the mean weight of quarters in circulation. A sample of 50 quarters has a mean weight of 5.632 grams and a standard deviation of 0.056 gram. Use a sing value to estimate the mean weight of all quarters. Also, find the 95% confidence interval for the average weight of all quarters. 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 G
