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…
