This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

See attached data file.

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

1. Perform a two-tailed hypothesis test on both the intrinsic and the extrinsic variable's data, using a .05 significance level.
2. Begin by creating a null and an alternate statement.
3. Use Microsoft Excel to process your data. Copy and paste the results of the output to your report in Microsoft Word.
4. Identify the significance level, the test statistic, and the critical value. State whether you are rejecting or failing to reject the null hypothesis statement.
5. In a separate paragraph, provide some information on when to use a t-test and when to use a z-test and why.
6. Also, provide some information about why samples are used instead of populations.

NULL HYPOTHESES (HO)
1. There is no significant difference in the intrinsic job satisfaction levels of the workers when grouped as to position.
2. There is no significant difference in the extrinsic job satisfaction levels of the workers when grouped as position.
Two-tailed hypothesis test on both the intrinsic and the extrinsic variables data, at .05 level of significance was the used.

Statistic used: t-test of difference between means
1. To test for difference in the intrinsic satisfaction level of the workers when grouped as to position using t-test of difference between means, the following were the results:
a) Test statistic used is t-test of difference between means
b) α = .05 level of significance
c) t value = 0.006444
d) critical value = ...
