    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:
     

    o   What is the significance level of the comparison?

    o   What was the alpha level you identified in Week 3?

    o   What was the means and variance for each variable?

    o   What was the test statistic?

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

    o   Was your test one-tailed or two-tailed?

    o   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.
