You want to estimate the mean weight of quarters in circulation. A sample of 60 quarters has a mean weight of 5.655 grams and a standard deviation of 0.062 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.       The estimate for the mean weight of all quarters is 5.655 grams. ​(Round to three decimal places as​ needed.) Find the​ 95% confidence interval for the mean weight of all quarters.     grams<μ
