Question
Please answer all....
the analysis of the data. use the following Distributions tool to identify the boundaries that separate the extreme samples from the sanples that the critical region is split across both tails of the distribution. The z-score boundaries at an Oz-3.29 and z 3.2 O 2-1.96 and z - To use the tool to identity the z-score boundaries, click on the icon with two orange lines, and slide the orange lines until the area in the critical region equals the alpha level. Remem ber that the probabality will need to be split between the two tails. To use the tool to help you evaluate the hypothesis, cick on the icon with on the critical values, and then place the purple line on the z statistic the purple fine, place the two orange lines The critical region is Oz-1.96 anda-196 O-258 and z z”3.29 and 1 -329 Suppose that the calculeted z statistic for a particular hypathesis test is 4.0s and the alpha is.001 This z statistic is the critical region. reject the null hypothesis, and he conclude the alternative hypothesis is probably correct 2-01
Explanation / Answer
alpha = 0.05
z=1.96 and z=-1.96
Slide it to -2 and 2 from the mean
z=3.29 and z=3.29
This z stat is outside the critical region.therefore the researcher will reject the null hypothesis
and he will not conclude....
