2. The graph portrays the decision criterion for a one-mean z-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 following: a) Rejection region. b) Non-rejection region. c) Critical value(s). d) Significance level. e) Confidence level. f) Identify the hypothesis test as two tailed, left tailed, or right tailed. A z = -1645 and z =1.645 . B. 5% C. Between z = -1645 and z =1.645 (non-inclusive) D 90% . E. Between z = -1645 and z =1.645 (inclusive) F. Two tailed G 95% . H Left-tailed . I. 10% J. Left of z = -1645 and right of z =1.645 (inclusive) K Right-tailed
