Question

In a survey of 200 adults in the town of Waskegon, 45 reported reading the online version of the Waskegon Bulletin the previous day. If 25,000 adults live in Waskegon, which number is the best estimate of the number of adults who read the online version of the Waskegon Bulletin the previous day?

a) 450
b) 1,125
c) 2,250
d) 4,500

Answer 1

To find the best estimate of the number of adults who read the online version of the Waskegon Bulletin the previous day, set up a proportion to solve for x. The best estimate is 5625, which is closest to option c) 2,250.

Step-by-step explanation:

To find the best estimate of the number of adults who read the online version of the Waskegon Bulletin the previous day, we can use proportions. We know that there were 45 adults out of a sample of 200 who read the online version. We can set up a proportion:

45/200 = x/25000

Cross multiplying, we get:

200x = 45 * 25000

Dividing both sides by 200:

x = (45 * 25000) / 200

Simplifying, we get:

x = 5625

So the best estimate of the number of adults who read the online version of the Waskegon Bulletin the previous day is 5625, which is closest to option c) 2,250.
