A random sample of size n is to be used to test the null hypothesis that the parameter θ of an exponential population equals θ0 against the alternative that is does not equal θ0. (a) Find an expression for the likelihood ratio statistic. (b) Use the result in part (a) to show that the critical region of the likelihood ratio can be written as ye¯ −y/θ ¯ 0 ≤ K? .

D. 1. A sample of size 16 is used in testing the null hypothesis that μ > 100. The sample results indicate that = 96 and s = 4. Test the null hypothesis using a significance level of .05. 2. What does the significance level tell us? That is, precisely what is it that has a probability of less than .05? Be specific.
