A recent survey of pet owners found that 53% of 100 randomly selected cat owners (population 1) and 63% of 100 independently, randomly selected dog owners (population 2) said they would perform cardiopulmonary resuscitation (CPR) on their pets in the event of a medical emergency. Determine a 95% confidence interval for the difference in the population proportion of pet owners who would provide CPR on their pet in the event of an emergency.
