Check for accuracy and respond the last questions 2. For this problem, use Chapter 11 Data Set 3. We want to know if urban and rural residents both have the same attitude toward gun control. a. What is the null hypothesis? The null hypothesis concludes that there is no difference in attitudes toward gun control between urban and rural residents. b. What is the research hypothesis? The research hypothesis suggests that there is a difference in attitudes toward gun control between urban and rural residents. c. Will you be conducting a one-tailed or a two-tailed test? Why? In this case I would conduct a two-tailed test because i’m interested in whether there is a difference in attitudes toward gun control between urban and rural residents, regardless of which direction that difference follows. e.- What is the p-value (hint: it is under “sig” in the output table)? The P-value is 0.44. Do you reject the null hypothesis or fail to reject the null? What do you conclude about urban and…

2 part question done in Excel. 1. Data are collected in a clinical trial evaluating a new compound designed to improve wound healing in trauma patients. The new compound is compared against a placebo. After treatment for 5 days with the new compound or placebo, the extent of the wound healing is measured and the date are show in the table below. Is there a difference in the extent of wound healing by treatment (Hint: Are treatment and the percent wound healing independent?) Run the appropriate tes at a 5% level of significance. 2. Use the data in Problem 1 and pool the data across the treatments into one sample of size n=250. Use the pooled data to test whether the distribution of the percent wound healing is approximately normal. Specifically, use the following distributions: 30%, 40%, 20%, and 10%. Run the appropriate test at a = 0.05.
