Using the z table, find the critical value (or values) for an α = 0.018 left-tailed test. A) -1.19 B) -2.37 C) -2.10 D) -1.05
Find the critical t-score (t) for the two tailed test with α-.01. a) t2.58 b) t3.01 c2.62 d) 2.65 e) none of these 14. 15.Therefore, the conclusion for this hypothesis test is: a) reject Ho at a-.05 and FTR Ho at a-o1 c) reject H° at α-.01 and FTR Ho at α-05 b) reject H, at α-.05 and α-.01 d) FIR h, at α-.05 and α-,01 e) none of these after in the percentage of cans showing discoloration 16. This...
You are performing a two-tailed test. If α = .004 , find the positive critical value, to three decimal places. zα/2 = You are performing a left-tailed z-test If α=.025, and your test statistic is z=−1.75, do you: Reject Null Hypothesis Fail to Reject Null Hypothesis
For a two-tailed test using z values at the .01 significance level we reject H0 if z ≤ -2.576 or if z ≥ 2.576. True or False
A. Critical Values for Hypothesis Tests (o known) a) For an upper tailed hypothesis test when a = .0197, then 2 = b) For a two-tailed hypothesis test when a = 0.0104, then 2a/2= c) For a lower-tailed hypothesis test when a = 0.0132, then-Za = B. Critical Values for Hypothesis Tests (o unknown) a) For an upper tailed hypothesis test at 27 d.f. and a = .025, then ta = b) For a two-tailed hypothesis test at 58 d.f....
You are performing a two-tailed z test. If α = .004 , find the positive critical value rounded to two decimal places.
What is the critical z value for a one sided test when α = .01 and n = 25? What is the critical z value for a two sided test when α = .01 and n = 25? What is the critical t value for a one sided test when α = .01 and n = 25? What is the critical t value for a two sided test when α = .01 and n = 25?
A researcher is using a two-tailed hypothesis test with α = .05 to evaluate the effect of a treatment. If the boundaries for the critical region are t = ± 2.080, then how many individuals are in the sample? n = 20 n = 22 n = 21 Impossible to determine without more information
