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 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 u = 4960. μl =

i) If Ho is rejected when X₁ ≤ 6. then what is the probability of type I error? ii) If H, is rejected when Σ2₁X₁ ≤ 6. then what is the probability of type I error? 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 10 μ = 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 (8)
