A new quality assurance process developed in Seoul by Mr Yu for a newly  introduced  Cement results in a mean strength of 5000 with a standard  deviation of 120 kilograms. In order for Mr Yu to test the null hypothesis that ? = 5000 against the alternative that ? < 5000, He random sampled 50 fragments of this cement and tested them. If his critical region was defined to be ? < 4970. What will be his probability of not committing type II error when ? = 4960.

Question

A new quality assurance process developed in Seoul by Mr Yu for a newly 
introduced  Cement results in a mean strength of 5000 with a standard 
deviation of 120 kilograms. In order for Mr Yu to test the null hypothesis that
? = 5000 against the alternative that ? < 5000, He random sampled 50 fragments
of this cement and tested them. If his critical region was defined to be ? < 4970. What
will be his probability of not committing type II error when ? = 4960.
