Final answer:
The best estimate for the number of adults in Waskegon who read the online version of the Bulletin the previous day is 5,625, which is calculated through a simple cross-multiplication of proportions based on the survey sample.
Step-by-step explanation:
The question is regarding estimating population proportions based on sample data. In the survey of 200 adults in the town of Waskegon, 45 reported reading the online version of the Waskegon Bulletin the previous day. To estimate how many out of the entire population of 25,000 adults read the online version, we use a proportion:
Sample Size: 200 adults
Sample Readers: 45 adults
Total Population: 25,000 adults
The proportion of adults in the sample who read the bulletin is 45/200. To estimate the number of adults in the total population, we set up a cross-multiplication:
45/200 = X/25,000
After cross-multiplying and solving for X, we find that:
X = (45 * 25,000) / 200 = 5,625
Therefore, the best estimate of the number of adults who read the online version of the Waskegon Bulletin the previous day is 5,625, which corresponds to option (c).
