10.2.8 Your answer is partially correct. Try again. A photoconductor film is manufactured at a nominal thickness of 25 mils. The product engineer wishes to increase the mean speed of the film, and believes that this can be achieved by reducing the thickness of the film to 20 mils. Eight samples of each film thickness are manufactured in a pilot production process, and the film speed (in microjoules per square inch) is measured. For the 25-mil film, the sample data...

Chapter 10 Section 1 Additional Problem 1 Consider the hypothesis test Ho: Mi = u2 against H: M1 < u2 with known variances (j = 11 and 02 = 6. Suppose that sample sizes nj = 10 and n2 = 16 and that Æj = 14.4 and 12 = 19.8. Use a = 0.05. (a) Test the hypothesis and find the P-value. (b) What is the power of the test...
