2) A new quality assurance process developed in Limpopo by Mr Masela for a newly introduced Sephaku Cement results in a mean strength of 5000 with a standard deviation of 120 kilograms. In order for Mr Masela to test the null hypothesis that μl 5000 against the alternative that μ< 5000, He random sampled 50 fragments of this cement and tested them. If his critical region was defined to be y < 4970. What will be his probability of not committing type II error when μ = 4960. A 32°C 9x3
