# Two-tailed hypothesis test

Perform a two-tailed hypothesis test on the intrinsic variable AND a two-tailed hypothesis test on the extrinsic variable's data using a .05 significance level for each.

Begin by creating a null and an alternate statement. Use Microsoft Excel to process your data. Copy and paste the results of the output to your report in Microsoft Word. Identify the significance level, the test statistic and the critical value. State whether you are rejecting or failing to reject the null hypothesis statement. Repeat the steps for the 2nd two-tailed hypothesis test.

In a separate paragraph, provide some information on when to use a t-test and when to use a z-test and why. Also, provide some information about why samples are used instead of populations.

Be sure to provide references in APA format for any resource you may use.

Unit 3 IP: The assignment is a hypothesis test for a single population mean of a quantitative variable equal to a given number. This is to be done twice. Test the hypothesis that the population mean of the intrinsic is equal to 5 or not. then separately test the hypothesis that the population mean of the extrinsic is equal to 5 or not. Use all 25 data rows for each! Since n<30, use a statistic! For this and any hypothesis test, I want you to number the five steps as in the book. Please provide the following summary table.

Write this as a coherent integrated report in Word with an introduction, description of methods, results, interpretation of results, and conclusion, with references.
