Over a 18 day period, daily measurements of silver yield from a mine us taken. The company has an original goal of the 60th percentile being more than 50 tons. From the 18 days, 8 days yielded less than 50 tons. No day yielded exactly 50 tons. Test to see if the company’s goal is upheld.

(a) State the hypothesis for testing this claim.

(b) Explain and show what test statistic you're using and how to get the p-value

(c) Give your conclusion. Explain.

Solutions

Expert Solution

Let p denotes the true proportion of daily measurements yielding less than or equal to 50 tons.

(NO MINI TAB) 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,...
