1) Find the critical z-value(s) for a right tailed test with α = .02 . Assume a normal population. (Round to the nearest hundredth. If more than one value is found, enter the smallest critical value.) 2) Find the critical t-value(s) for a two-tailed test with n = 12, α = .05 . Assume a normal population. (Round to the nearest thousandth. If more than one value is found, enter the smallest critical value.) 3) Find χ2R for a right-tail...

The z statistic for a one-sided test is z* = 2.327. This test is A. not significant at α = .005 but significant at α = .01 level B. significant at α = .005 but not at α = .01 level C. significant at all levels D. not significant at either α = .005 nor α = .01 level E. not significant at all levels F. significant at both α = .005 and α = .01 level An experiment was...
You are performing a left-tailed z-test If α = .05 , find the critical value, to two decimal places.
Find z* for each of these situations, taking into account whether the test is one-sided or two-sided. Then find the p-value, indicating its relation to alpha. Finally, determine if the hypothesis test would lead to rejection of the null. Test statistic(z) = -2.84, Ho : p = .10, Ha : p < .10, α = .06
