A machine produces metal pieces that are cylindrical in shape. A sample of pieces is taken, and the diameters are found to be 0.94, 0.96, 0.97, 1.05, 0.99, 0.98, 1.02, 0.94, and 0.94 centimeters. Find a 90% confidence interval for the mean diameter of pieces from this machine, assuming an approximately normal distribution. Click here to view page 1 of the standard normal distribution table.
