You want to estimate the mean weight of quarters in circulation. A sample of 60 quarters has a mean weight of 5.625 grams and a standard deviation of 0.067 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 5.625 grams. (Round to three decimal places as needed.) Find the 95% confidence interval for the mean weight of all quarters. grams<μ< *** (Round to three decimal places as needed.) grams
