The Gidget Company makes widgets. If the production process is working properly, it turns out that the widgets are normally distributed with a hean length of at least 2.6 feet. Larger widgets can be used or altered but shorter widgets must be scrapped. You select a sample of 25 widgets, and the mean length is 2.46 feet and the sample standard deviation is 0.16 foot.
