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? * answer asap! *

Order the two data sets from least to greatest:

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

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

To find the median of each data set, add the number of terms by 1 and divide by 2 to determine which term is the median:



The third term of each data set will be the median.

Dealership 1's median is $42,000, and dealership 2's median is $28,000.

To find the mean of each data set, add all of the terms, then divide by the amount of terms.

Dealership 1:



Dealership 2:



Dealership 1's mean is $53,800, and dealership 2's mean is $38,600.

The measure of center that will provide the most accurate estimate of the costs of cars purchased at the two dealership is the mean, as it provides the average cost of a car.
