Provide analysis of the below scenario

Business Decision Making Project

Purpose of the Signature Assignment

The purpose of this assignment is to provide students with the opportunity to demonstrate mastery of the ability to apply statistical concepts to business situations and to implement the data-driven decision-making process. The Signature Assignment is due in Week 6. The assignment will be a scenario for which they will prepare a power point of at least 8-10 slides for presentation in Week 6. The presentation will address

• Clearly define the problem or issue being addressed. Provide a brief background of any research that the team may have found that might affect the research hypothesis.
• Create a research hypothesis based on the information and data provided in each scenario. Each team will be given data within the scenario or a data set (Microsoft® Excel® document with two columns of data (just the numbers, as you must decide what values the data represent; that is, what is the scale of the data and what does that scale represent. If the data is 8.7, for example, is that a continuous score on a scale from 1-10 and what does that scale represent? For example, is it an assessment score, a rating, or some other representative measure?). This means you are going to test one thing against another, such as which method works best (step 1 of the steps to hypothesis testing).
• State the null and research hypotheses. Explain whether these hypotheses require a one-tailed test or two-tailed test, and explain your rationale.
• Use the data set that is provided with this specification description. The same data set will work for all scenarios. The data set is the sample you will use. Sample size will be 30 for each group, which are provided in your data set. Explain what type of sampling was used to gain these data.

• Explain your conclusion and its implications

Example

You have a hypothesis that two drugs have different effects on lowering anxiety. You would have anxiety scores (1-10) for drug A and anxiety scores for drug B (all after 4 weeks of treatment) to run inferential analysis for after 4 weeks.

• Null hypothesis is H0: drug A = drug B
• Research hypothesis is H1: drug A ≠ drug B
• Dependent variable: anxiety score changed after treatment
• Independent variable: drug treatment

If you do not state a direction in your hypotheses (better than or worse than), the hypothesis test will be a two-tailed test. You are looking for differences in either direction. You would set your alpha level of .05 and have a sample for each group of 30 people that were volunteers for the study.

Research Scenarios for Each Team

Team A

• The Foundation for Empirical Research has had a law suit filed against it for sexual harassment under the Hostile Work Environment Harassment section of the California Fair Employment and Housing Act. One of the conditions of the settlement of the suit was that all employees must take a six-hour course conducted by a court-appointed attorney and that the group must achieve a mean exit score that meets the state-mandated mean of 7. Was the Exit score average 7 or above for the second assessment so that the Foundation complies with the mandate of the law suit?

Group 1 is the initial assessment and Group 2 is the exit exam. Calculate the means and standard deviations of both assessments.
