The CEO of the diabetes clinic reviewed your recommendation on whether to continue with the disease management program based on your analysis of the pilot study that was the focus of Assignment 4.1. She indicated an appreciation for your work and said she was still evaluating your recommendation but wanted some additional input to help her make a final decision. She was unclear as to the purpose and meaning of the p-value that was reported in the results. She also was interested in your opinion on a research article she read on a different diabetes disease management program. The research reported that the distance patients had to travel to participate in the program had a negative effect on the success of the program. The research reported that this finding was statistically significant. The CEO was having trouble understanding what travel distance had to do with disease management and wanted your opinion on the interpretation of this finding. She was interested in knowing whether patient travel time should be included in your analysis (Assignment 4.1) as a factor of success. Prepare a brief memo (in lay terms) to the CEO of the diabetes clinic (Dr. Wilhelmina Smith) answering her questions about your analysis and the research report she read. Specifically, your memo should include the following: 1. Discuss the p-value associated with the test statistic presented in the analysis in Assignment 4.1, explaining what the p-value means and how it should be interpreted in the context of evaluating the disease management program. 2. Additionally, explain the meaning of statistical significance in the context of the research report your CEO mentioned regarding the relationship between travel time and the success of a disease management program. Answer her question regarding whether you should add patient travel time to your analysis of the success of your disease management program. Activity 4.1 You are the director of a diabetes clinic that has recently completed a pilot for a new disease management program intended to reduce blood glucose levels in the participants. In developing the pilot study, you set out to demonstrate that the program will be effective in reducing average blood glucose levels for the program’s participants. You hope to demonstrate the value of the program to your CEO by presenting the findings from a hypothesis test based on the results from the pilot study. After extensive preparation, including a comprehensive review of the literature and discussions with subject matter experts, the specifics of the disease management program were devised. The program consisted of individual counseling and education regarding lifestyle changes and healthy eating choices. The program recruited 50 patients who were seen twice a month, at which time they received individual counseling, along with having their blood sugars checked and tracked. The pilot lasted six months and required a fairly large resource commitment on the part of the clinic. Prior to beginning the program, participants had their blood glucose level drawn. The expectation was that the average blood glucose level of the group at the end of the pilot period would be lower than the average blood glucose level at the beginning of the pilot. Over the course of the six-month pilot period, the program went well. The participants were engaged and seemed motivated, with very few missed appointments and no dropouts along the way. While the program ran smoothly the cost of the program compared to its value would continue to be a factor in whether the program would be renewed. The clinic expressed its commitment to continue the program if the program was found to be successful in reducing participants’ blood glucose levels. You are asked to prepare a report to the clinic’s CEO detailing the value of the disease management intervention. In collecting your data, you found that at the beginning of the pilot the group’s average blood glucose level was 257.5 milligrams per deciliter. At the end of the pilot period, the average blood glucose level for the group was 240 milligrams per deciliter. You have some knowledge of statistics and want to be pretty conservative in your analysis, so you set your desired alpha level at 0.01. You asked a statistician friend to run the numbers and she reported back with the following statistics: t-test value: -3.68 p-value:
