Final answer:

In this response, we explain how to calculate the expected number of people who know how to swim based on a given statistic for different group sizes.


Explanation:

60% of people in North America know how to swim. In a classroom with 40 people, you would expect 24 to know how to swim (40 x 0.6). In a school with 2,000 people, you would expect 1,200 to know how to swim (2000 x 0.6).

These numbers are predictions based on the given statistic. They represent the expected proportion of people who know how to swim in each group.
