Answer
Estimate: 100,000; Exact: 153,223
Work Step by Step
To estimate, we first round 721,523 to 700,000 and round 568,300 to 600,000. We subtract the rounded numbers to find the estimated difference in population.
700,000 - 600,000 = 100,000
To find the exact difference, we subtract the actual population of Wyoming from the actual population of Alaska.
721,523 - 568,300 = 153,223
