Step 1: Test Set-up

The next test is a t-test for unequal variance. Here is the problem: The human resources department at Sue, Grabitt, and Runne also tracks the cost of one-bedroom apartments in two popular neighborhoods, NoBo and SoBo. The general perception of long-time residents is that rents are probably lower in SoBo. They hope to determine whether the average rent for a one-bedroom apartment is lower in SoBo than in NoBo. The results of their survey are shown in Tables 18 and 19:

Step 2. Select the Level of Significance, α

A 5 percent significance has been selected.

Step 3. State the Null Hypothesis (H0) and Alternate Hypothesis (H1)

H0:

H1:

Step 4. Compose the Decision Rule

Step 5. Calculate the Value of the Test Statistic, p-value, and estimate statistical power

Use G*Power to calculate statistical power.

Step 6. Decide and Report
