3. 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
(a) what are the mean and the median of each data set?
(b) which measure of center will provide the most accurate estimate of the costs of cars purchased at the two dealerships?

(a)   Mean of Dealership 1: 53800

Median of Dealership 1: 42000

Mean of Dealership 2: 38600

Median of Dealership 2: 28000

(b)   the median because there are outliers

(a) The Mean of Dealership 1: 53,800

 The Median of Dealership 1: 42,000

 The Mean of Dealership 2: 38,600

The Median of Dealership 2: 28,000

(b) the median is the most reliable because there are outliers involved in the question

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
