# Hypothesis Testing: Intrinsic & Extrinsic Job satisfaction

See attached data file.

Using AIU's survey responses from the AIU data set, complete the following requirements in the form of a report:

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.

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.

Objectives

# Compute mean, median, mode for a set of data.

# Formulate null and alternative hypotheses for applications involving a single population mean, proportion, or variance.

# Use effective communication techniques.

#### Solution Summary

The solution provides step by step method for the calculation of test statistic for the comparison of population mean. The solution also provides information on when to use a t-test and when to use a z-test and why samples are used instead of populations. Formula for the calculation and Interpretations of the results are also included. Interactive excel sheet is included. The user can edit the inputs and obtain the complete results for a new set of data.
