Open the Nursing Home workbook from the Chapter06 folder. Save the workbook as Nursing Home Beds to the same folder. b. Write down a set of hypotheses for exploring the question of whether the numbers of beds in rural and nonrural homes differ. c. Apply a two-sample t test to the data. Report your results assuming a pooled estimate of the standard deviation and assuming an unpooled estimate. What are the p value and confidence interval under each assumption? d. Create a boxplot of the Beds variable for the different locations. Do the plot and the descriptive statistics give you any help in determining whether to use a pooled or a nonpooled test? Explain your answer. e. Apply the Mann-Whitney test to the data. What are your hypotheses? What is your conclusion? Include information on the p value and confi dence interval in your discussion. f. Save your changes to the workbook and then write a report summarizing your results. Do your conclusions differ on the basis of which test you apply? Which statistical test would you report and why?
