Explanation / Answer

Solution:

(a)

Exact value that is 49% of 2286 = 0.49 × 2286 = 1120.14

(b)

Option (B) is correct.

"No, the result from part (a) could not be the actual number of adults who said that they play baseball because a count of people must result in a whole number. "

We get 1120.14, which is not a whole number.

(c)

The actual number of adults who play baseball could be 1120.

(d)

Percentage of respondents said that they only play hockey = (231/2286) × 100 % = 10.10%
