Suppose that X1......Xn form a random sample from a normal distribution for which the value of the mean mu is known and the value of the variance sigma-squared is unknown; and that the following simple hypotheses are to be tested: H0: sigma-squared = 2, H1: sigma-squared = 3. For n = 8, find the value of the constant c so that the test that will reject H0 if the sum when i = 1 to n (Xi - mu)^2 > c, will have level of significance .01 |
