Imagine you are an executive for an organization of your choice, and you are preparing a presentation for the board of directors about the organization’s direction.
Create a PowerPoint presentation (approximately 10 to 15 slides), with speaker notes, in which you address the following components:
- Describe the organizational structure and design.
- Examine the organization’s differentiation and growth strategy.
- Analyze strategic options and a management approach the organization uses as it relates to the organization’s goals and strategies.

Format your presentation consistent with APA guidelines. All sources used must be referenced; paraphrased and quoted material must have accompanying in-text citations in the proper APA format.
Question
To test the hypothesis that students who finish an exam first get better grades, Professor Hardtack kept track of the order in which papers were handed in. The first 25 papers showed a mean score of 77.1 with a standard deviation of 19.6, while the last 24 papers handed in showed a mean score of 69.3 with a standard deviation of 24.9. Is this a significant difference at α = .05?
(a) State the hypotheses for a right-tailed test.
(b) Obtain a test statistic and p-value assuming equal variances. Interpret these results.
(c) Is the difference in mean scores large enough to be important?
(d) Is it reasonable to assume equal variances?
(e) Carry out a formal test for equal variances at α = .05, showing all steps clearly.
