D. 24,800
E. None of the above

Answer 1

The best estimate for the number of adults in Waskegon who read the online version of the Waskegon Bulletin the previous day is approximately 5,600, which corresponds to option A.

Step-by-step explanation:

The student's question relates to estimating a population proportion based on sample data. In the survey, 45 out of 200 adults read the online version of the Waskegon Bulletin the previous day. To estimate the number of adults in the entire town who read it, we use a proportion:

(45 adults read the bulletin in the sample of 200) / (200 adults in the sample) = (x adults read the bulletin in Waskegon) / (25,000 adults in Waskegon).

Using a cross-multiplication, we get 45/200 = x/25,000. Solving for x gives us:

x = (45/200) * 25,000

x = 5,625

The best estimate is 5,625 adults, which is approximately 5,600. Hence, option A is the best estimate.
