Inferential Statistics Research Project
Part 2
Analyze the data from Part 1 using Microsoft® Excel® software.Â
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?Â
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.
