Question

An example of a null hypothesis in single hypothesis testing is ________ and that of composite or joint hypothesis testing is ________. H_0: mu _1 = mu _2 = 0; H_0: mu = 0 H_0: Mu_1 = mu_2 = 0; H_0: mu notequalto 0 H_0: Mu notequalto 0; H_0: mu _1 = mu _2 = 0 H_0: mu = 0; H_0: mu _1 = mu _2 = 0 H_0: mu notequalto 0; H_0: mu _1 notequalto mu _2 notequalto 0 When an alternative hypothesis is stated as Ha: mu notequalto 0, it means a _______ test. one-tailed two-tailed composite only (a) and (c) of the above only (b) and (c) of the above When an alternative hypothesis is states as Ha: mu > 0, it means a _______ test. one-tailed or directional directional or upper-tail directional or lower-tail only (a) and (b) of the above only (a) and (c) of the above A two-tail test means that there is/are _________ rejection region(s) and a one-tail test means that there is/are _______ rejection region(s). two; one two; two one; one one; two more than 2; only one A significance level, a, is a measure of Type I error. a measure of Type II error. equal to 1 minus a confidence level. only (a) and (c) of the above. only (b) and (c) of the above. Rejecting the null hypothesis when it is in fact true involves an error called ______. Type I error measured by a significance level. Type II error measured by a significance level. Type I error measured by a power of the test. Type II error measured by a power of the test. Type I error measured by a confidence level.
