Question
Six measurements are taken of the thickness of a piece of 18-guage sheet metal. The measurements (in mm) are: 1.316, 1.308, 1.321, 1.303, 1.311, 1.310

Make a boxplot of the six values.
Should the t distribution be used to find 99% confidence interval for the thickness? If so, find the confidence interval. If not explain, why not.
Six independent measurements are taken of the thickness of another piece of sheet metal. The measurements this time are: 1.317, 1.318, 1.301, 1.307, 1.374, 1.323. Make a boxplot of these values.
Should the t distribution be used to find 99% confidence interval for the thickness? If so, find the confidence interval. If not explain, why not.
