Find the appropriate rejection regions for the large-sample test statistic z in these cases. (Round your answers to two decimal places. If the test is one-tailed, enter NONE for the unused region.)
(a) A right-tailed test with 𝛼 = 0.01
z > |
z < |
(b) A two-tailed test at the 10% significance level
z > |
z < |
The critical value of z is term linked to the area under the standard normal model.A critical value of z is sometimes written as za, where the alpha level, a, is the area in the tail. For example, z.10=1.28.   A rejection region (or critical region) of the sampling distribution is the range of values for which the null hypothesis is not probable.  If a test statistic falls in this region, the null hypothesis is rejected. A critical value z0 separates the rejection region from the nonrejection region.  The rejection region is to the right of z0 = 2.575. z.10 = 1.28. α=tail area&# ... See the full answer
