Calculate the test statistic. Here, we'll be using the formula below for the general form ofthe test statistic. 3. Determine the p-value. The p- value is the area under the standard normal distribution that is more extreme than the test statistic in the direction of the alternative hypothesis. 4. Make a decision. pr g a reject the null hypothesis. pr > a fail to reject the null hypothesis. 5. Statea "real world" conclusion. Based on your decision in step 4, write a conclusion in terms of the original research question. General Form ofa Test Statistic When using a standard normal distribution (i.e., 2 distribution), the test statistic is the standardized value that is the boundary of the p-value. Researchers want to know if there is evidence that the mean monthly rental rate of a two- bedroom apartment in Philadelphia, Pennsylvania, is different from $2200. Use the vestep hypothesis testing procedure that is outlined below to conduct a hypothesis test to determine if there is evidence that the population mean is different from $2200. Because the sample size is large, the sampling distribution will be approximately normal and you can use the 2 distribution to nd the p-value. Use a 0.05 alpha level.

This is slightly different from the five step procedure that we used when conducting randomization tests. 1. Check assumptions and write hypotheses. The assumptions will vary depending on the test. In this lesson we'll be confirming that the sampling distribution is approximately normal by visually examining the sampling distribution. In later lessons you'll learn more objective assumptions. The null and alternative hypotheses will always be written in terms of population parameters; the null hypothesis will always contain the equality (i.e., =). 2 Calculate the tact statistic Hara
