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.

Part 3

Create a 12- to 15-slide presentation using the information you gathered and submitted in Weeks 3 & 4. Include the following:

· Describe the problem, and provide some brief background about the situation.

· Explain the research hypothesis.

atleast 100 words for speaker notes

· Describe your sample and your sampling method.

· Explain the four steps of the research process you followed, and define the critical value and the test statistic your analysis provided.
