Metalcraft Enterprises, Inc. manufactures precision tubular parts. One such part is a cylindrical tube with specified diameter of 4 cm. Suppose a random sample of 16 of these tubes yields an average diameter of 3.985 cm with a standard deviation of 0.01 cm. 1.Based on the sample data, the 99% confidence interval estimate of the mean diameter, μ, of these tubes is: 2. Which of the following statements is true if the 99% confidence interval is used to test H0:...
