Question

Suppose you are conducting a hypothesis test with the null hypothesis Ho: -5 versus the alternative hypothesis : > 5. You collect a sample from the population of interest and calculate your test statistic. Assuming the null hypothesis is true, assume your test statistic is normally distributed such that you can compare its value to the standard normal distribution Your hypothesis test is ,meaning you are conducting a test. Considering the null and alternative hypotheses given, use the Distributions tool to identify the boundary that separates the extreme samples from the samples that are consistent with the null hypothesis. Use an an alpha level = .05. To use the tool, slide the orange line until the area in the rejection region equals the an alpha level. Remember that because the alternative hypothesis contains "greater than" (>), the rejection region will be in the right tail; that is, you will reject the null hypothesis for very large values of the test statistic Standard Normal Distribution Mean = 0.0 Standard Deviation-1.0 5000 5000 -4 0.0000

Explanation / Answer

Your hypothesis test is Testing for Single Mean, meaning you are conducting a Right - Tail Test

Z-scrore boundary is 1.6449 Correct Answre: Option (B) Z =1.6449

The Reject Region is Z > 1.6449

Z-scrore boundary is -2.5758 and 2.5758 Correct Answre: Option (B) Z = -2.5758 and 2.5758

The reject region is Z < -2.5758 and Z > 2.5758

If the an alpha level decreases, the size of the rejection region is decrease, casuing the test become more stringent
