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: u = 12 against H1:µ< 12 using a random sample of n = 4 specimens. Calculate the P-value if the observed statistic is x= 11.5. Round your final answer to five decimal places. Show all the necessary solutions.
