Question

The graph portrays the decision criterion for a one-mean x-test. The curve in the graph is the normal curve for the test statistic under the assumption that the null hypothesis is true. Determine the a) rejection region. b) nonrejection region. c) critical value(s). d) significance level. e) confidence level. f) Identify the hypothesis test as two tailed, left tailed, or right tailed. The rejection region is The nonrejection region is The critical value(s) are The significance level is Identify the hypothesis test as two tailed, left tailed, or right tailed. The confidence level is A. 50% B. Right-tailed C. 5% D. 10% E. Two tailed F. Left of x = -1645 and right of x = 1.645 (inclusive) G. x = -1645 and x = 1.645 H. Between x = -1645 and x = 1.645 (inclusive) I. 95% J. between x = -1645 and x = 1.645 (non-inclusive) K. Left tailed

Explanation / Answer

The rejection region is F

The non rejection region is H

The critical values are G Z=-1.645,Z=1.645

The signifcance level is D

Identfy the hypothesis test as two tailed left or right tailes--- E

The confidence level is ----A
