A textile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12kilograms with a standard deviation of 0.5 kilograms. The company wishes to test the hypothesis H0: µ = 12 against H1: µ < 12using a random sample of n = 4 specimens. Calculate the P-value if the observed statistic is x = 11.5. Round your final answer tofive decimal places. Show all the necessary solutions.P-value: Blank 1Blank 1Add your answer

In the second experiment a beam is simply supported at its two ends then loaded in the middle as seen in Figure 2 below. A dial gauge is used to measure the deflection at the middle, while a gauge on each end is used to measure the inclination of the beam at the supports (to compare to theoretical values).
