A textile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. The company wishes to test the hypothesis Ho:μ = 12 against H₁:μ< 12, using a random sample of 4 specimens. Round your answers to 4 decimal places. (a) What is the type I error probability if the critical region is defined as < 11.5 kilograms? The type I error probability is i (b) Find for the case where the true mean elongation is 11.28 kilograms. B = i (c) Find for the case where the true mean is 11.5 kilograms. B = = i
