You are performing a two-tailed test.
If α=.05α=.05, find the positive critical value, to three decimal
places.
zα/2=zα/2=
Solution:
Given that,
This is two tailed test
= 0.05
/ 2 = 0.05 / 2 = 0.025
Z/2 = Z 0.025 = 1.960
The positive critical value is 1.960

You are performing a left-tailed t-test with a sample size of 21. If α=.05α=.05, and your test statistic is t=−2.89t=-2.89, do you: fail to reject the null hypothesis reject the null hypothesis You will either want to either: Calculate the critical value and compare the test statistic to it. Calculate the p-value and compare it to the significance.
