A survey was conducted to measure worker opinions about pets in the workplace. Those who worked in pet-friendly offices were found to believe it improves the atmosphere in the workplace. The majority of workers in pet-friendly workplaces consider the policy to be positive. Of 80 workers surveyed, 75% reported decreased worker stress levels, while 90% of 50 managers reported decreased stress levels. If you were to compare workers and managers using two 95% confidence intervals, would you conclude the true proportions are different for all workers and all managers? Because the intervals A. do not overlap, B. overlap, the true proportions A. are not considered different B. are considered different for managers and workers.
