Exam #3, Q22: Florence Nightingale is remembered for is her role as a social activist and her use of statistical data to push medical reform. This problem will evaluate the data she used to argue for more sanitary conditions in camps and hospitals during the Crimean War. She argued that because the camps and hospitals were unsanitary, more soldiers were dying of preventable diseases than of wounds caused by battle. The data below summarize the average number of deaths from preventable disease and from wounds at each month for 24 months during the war. Use these data in Rguroo to construct a 95% confidence interval for the difference in the average number of deaths due to preventable disease and wounds from battle. Sample Size (n) Sample Mean (x) Sample s.d. (s) Deaths from Disease 24 603 717 Deaths from Wounds 24 73 87 1. Comment on whether the sample size condition has been met for this type of inference. Are there any assumptions we should make? 2. What is the point estimate equal to? 3. What are the upper and lower limits of the confidence interval? 4. Interpret this confidence interval. For full credit, explain why or why not these data support Florence Nightengale's argument
