315 Week 4 Inferential Research and Statistics Project, Part 2
Analyze
the data from Part 1 using Microsoft® Excel®

·
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
