Reference no: EM1320902

A production process assumes a population mean of µ = 80.

Periodically this process is tested.
A Sample of n =100 is taken.
The standard deviation = 8

The firm has already decided that any sample mean below 78 or above 82 will signal the workers that the process is not working properly.

Using this information, calculate alpha risk (probability of Type I error).
