1. A realtor who's fresh out of school receives a job offer from two different firms. The two firms are very similar, but there seems to be a difference in the prices of homes sold. Over the past year, the first firm has sold 250 homes for an average of $200,000 with a variance of $15,000. During that same time frame, the second firm has sold 200 homes for an average of $300,000 with a variance of $35,000. Are the firms statistically similar? Which one should the realtor join? Why?
