Need repair to assignment-deliverable 7 – statistical analysis report

I need to get an “A” on this assignment or I will fail. 

Here is what the professor said about my assignment…” 

Good work Jeffrey.  You fully explained the scenario and data provided with only minor errors.  However, no steps are shown for how you computed the measures of center and measures of variation.  The confidence interval is correctly calculated and explanations demonstrate a mastery of understanding.  Your explanations are good when explaining a hypothesis test, but a few key steps or components are incorrectly calculated.

When defining the variables, each should only have one level of measure, you must choose which fits best for each.

Be sure to show your work in Excel for finding each level of measure and each level of center.  You may leave off any unnecessary calculations.

You have an error in your calculation for the test statistic in th hypothesis test which also led to an incorrect P-Value.

Here are the instructions: 

Instructions

You are currently working at NCLEX Memorial Hospital in the Infectious Diseases Unit. Over the past few days, you have noticed an increase in patients admitted with a particular infectious disease. You believe that the ages of these patients play a critical role in the method used to treat the patients. You decide to speak to your manager, and together you work to use statistical analysis to look more closely at the ages of these patients.

You do some research and put together a spreadsheet of the data that contains the following information:

• Client number
• Infection disease status
• Age of the patient

You are to put together a PowerPoint presentation that explains the analysis of your findings which you will submit to your manager. The presentation should contain all components of your findings. For review, the components of the report should include:

1. Brief overview of the scenario and variables in the data set
2. Discussion, calculation, and interpretation of the mean, median, mode, range, standard deviation, and variance
3. Discussion, construction, and interpretation of the 95% confidence interval
4. Explanation of the full hypothesis test
5. Conclusion
