The two data sets show random samples of the costs, in dollars, of cars purchased at two dealerships yesterday.

Dealership 1: {25,000,42,000, 37,000, 45,000, 120,000}

Dealership 2: {28,000, 95,000, 18,000, 19,000, 33,000}

1. What are each data set's mean and median?
2. Which measure of center will provide the most accurate estimate of the costs of cars purchased at the two dealerships?
