Part 2

Analyze the data from Part 1 using Microsoft® Excel® software.

Write a 700- to 875-word paper that includes the following information:

Describe what method you are using to compare groups.

Copy and paste the output into a Microsoft® Word document, and also answer the following questions:

What is the significance level of the comparison?

What was the alpha level you identified in Week 3?

What was the means and variance for each variable?

What was the test statistic?

What was the critical value for both the one- and two-tailed test?

Was your test one-tailed or two-tailed?

Were you able to reject the null hypothesis? In other words, did you prove there was a difference?

Talk about what these results mean in everyday language and in context to your chosen scenario.

Make a recommendation based on the findings.

Format your paper according to APA guidelines.
