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 O.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 l error probability if the critical region is defined as I < 11.5 kilograms? The type l error probability is i 0.02275 (b) Find B for the case where the true mean elongation is 11.27 kilograms. ß = i (c) Find ß for the case where the true mean is 11.5 kilograms. i
