(All Steps) When a certain production process is operating properly, it produces items that each have a measurable characteristic with mean 122 and standard deviation
Question: When a certain production process is operating properly, it produces items that each have a measurable characteristic with mean 122 and standard deviation 9. However, occasionally the process goes out of control, and this results in a change in the mean of the items produced. Test the hypothesis that the process is presently in control if a random sample of 10 recently produced items had the following values: 123, 120, 115, 125, 131., 127, 130, 118, 125, 128
Specify the null and alternative hypotheses, and find the p value.
