Answer:

Sample A Estimate: 330

Sample B Estimate: 420

Sample C Estimate: 360

Median: 360

Range: 90

Step-by-step explanation:

For the sample estimate, multiply 600 by 11/20, 7/10, and 3/5 in order.

600 * 11/20

6600/20

330 people for Estimate A.

600 * 7/10

420/10

420 people for Estimate B.

600 * 3/5

1800/5

360 people for Estimate C.

330, 360, 420

360 is the median of these estimates.

420 - 330 = 90

90 is the range of these estimates.
