The thickness of eight pads designed for use in aircraft

Reference no: EM13633741

The thickness of eight pads designed for use in aircraft engine mounts are measured. The measurements are 41.83, 42.68, 41.01, 41.37, 41.83, 40.50, 41.70, and 41.42. Assume the thicknesses are a sample from an approximately symmetric distribution.

Check the data to determine whether they are from a population that follows a normal distribution.

Regardless of your answer in part a, carry out an appropriate nonparametric test to determine whether the mean thickness is greater than 41. Use = .05.
