A real estate agent looks over the 40 listings she has in a particular zip code and finds that 80% of them have swimming pools. a) Check the assumptions and conditions for inference on proportions. b) If it's appropriate, find a 99% confidence interval for the proportion of houses in this zip code that have swimming pools. a) Check the assumptions and conditions for inference on proportions. Select all conditions that are met below. The Success/Failure Condition The Randomization Condition The 10% Condition No conditions are met. Select all assumptions that are justified below. The Independence Assumption The Sample Size Assumption No assumptions are justified. b) If it's appropriate, find a 99% confidence interval for the proportion of houses in this zip code that have swimming pools. If it's not appropriate, explain why. O A. The 99% confidence interval is ( )- B. Finding a confidence interval is not appropriate because the Independence Assumption is not justified. OC. Finding a confidence interval is not appropriate because the Sample Size Assumption is not justified. O D. Finding a confidence interval is not appropriate because neither the Independence Assumption nor the Sample Size Assumption is justified.

Select all conditions that are met below. The Success/Failure Condition The Randomization Condition The 10% Condition No conditions are met. Select all assumptions that are justified below. The Independence Assumption The Sample Size Assumption O No assumptions are justified. b) If it's appropriate, find a 99% confidence interval for the proportion of houses in this zip code that have swimming pools. If it's not appropriate, explain why. O A. The 99% confidence interval is ( O B. Finding a confidence interval is not appropriate because the Independence Assumption is not justified. O C. Finding a confidence interval is not appropriate because the Sample Size Assumption is not justified. O D.
