A textile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 15 kilograms with a standard deviation of 1.2 kilograms. The company wishes to test the hypothesis, Ho: u= 15 H: u<15 Using a random sample of four specimens. Suppose the random sample is from a normal population. What is the type I error probability, if the critical region is defined as < 13.5 kilograms? (Sonuç virgülden sonra 4 basamak olarak verilecektir.)
