Suppose a veterinarian wants to estimate the difference between the proportion of cat owners who are single and the proportion of dog owners who are single. Of the pet owners that visit any of the veterinarian clinics in her city regularly, she identifies 3872 pet owners that exclusively have cats and 4108 pet owners that exclusively have dogs. From this list of pet owners, she surveys 115 randomly selected cat owners and 105 randomly selected dog owners and asks each of them if they are single or married. Her findings are summarized in the table. Population Population Sample Number Sample description size of successes proportion 1 n = 115 x1 = 45 B1 = 0.39130 dog owners x2 = 38 P2 = 0.36190 Calculate the upper and lower limits (bounds) for a large sample 95% z-confidence interval for the difference in two population proportions, Pi - P2. Give each of your answers with three decimal places of precision. cat owners 2 hI= 105 lower limit = upper limit = Then, complete the following sentence to state the interpretation of the confidence interval
