A manufacturer produces candy bars. A sample of pieces is taken, and the length of the bars are found to be 2.00, 1.75, 1.5, 1.4, 1.0, 2.0, 2.0, 2.0, and 2.00 centimeters. Find a 90% confidence interval for the mean length of pieces from this candy machine, assuming an approximately normal distribution.

A random sample of 12 ballistic missiles are taken in a study of the Fluid Dynamics under Wind Tunnel. Measurements on the Normalized Reynolds Coefficient are made for each of the 12, yielding an average value of 48.50 with a sample standard deviation of 1.5. Assuming the measurements to be normally distributed, construct a 90% confidence interval for the mean Normalized Reynolds Coefficient.
