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 n = 4 specimens. Calculate the P-value if the observed statistic isī = 11.1. Suppose that the distribution of the sample mean is approximately normal. Round vour fnal answerto five decimal places (e g 98 76543)
