True or False. a If the p-value for a test is .036, the null hypothesis can be rejected at the = .05 level of significance. b In a formal test of hypothesis, is the probability that the null hypothesis is incorrect. c If the p-value is very small for a test to compare two population means, the difference between the means must be large. d Power( ) is the probability that the null hypothesis is rejected when = . e Power() is always computed by assuming that the null hypothesis is true. f If .01 < p-value < .025, the null hypothesis can always be rejected at the = .02 level of significance. g Suppose that a test is a uniformly most powerful -level test regarding the value of a parameter . If a is a value in the alternative hypothesis, (a ) might be smaller for some other -level test. h When developing a likelihood ratio test, it is possible that L( 0) > L(). i 2 ln() is always positive.
