Remember that the probability will need to be split between lines the icon with the purple line, place the two orange To use the tool to help you evaluate the hypothesis, click on on the critical values, and then place the purple line on the z statistic

Explanation / Answer

All answers with proper explanations below:

When a researcher sets alpha = .05, he is willing to accept a 5% probability or less that he rejects the null hypothesis when it is actually true

The z-score boundries at an alpha level of alpha = .05 are:

b. Z = 1.96, and z = -1.96 ( note since it is 2 tailed test we have 2 Zs)
c. The critical regsion is Z>=1.96 and Z<=-1.96
d. For alpha = .001, it is b. Z = -3.29 and 3.29
e,g,h. Suppose that the calculated z-statistic for a particular hypothesis test is 4.12, and alpha = .01. This z-statistic is inside the critical region. Therefore, the researcher will reject the null hypothesis and he will conclude that the alternative hypothesis is probably correct
