You want to estimate the mean weight of quarters in circulation. A sample of 50 quarters has a mean weight of 5.638 grams and a standard deviation of 0.066 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 of all quarters is__grams (Round to three deci,al as needed) Find the 95% confidence interval for the mean weight of all quarters ___grams<Y<__grams (Round to three decimal places as needed)
