Question

It may seem like everyone owns a smartphone, but that isn't necessarily true. In fact, a recent Pew Research poll indicated that only approximately 68% of Americans own a smart phone. In random, independent samples of 11 Americans, what is the average number who will own a smart phone?

Answer 1

To find the average number of Americans who own a smartphone in random, independent samples of 11 Americans, multiply the percentage of smartphone owners by 11 and round to the nearest whole number.

Step-by-step explanation:

To find the average number of Americans who own a smartphone in random, independent samples of 11 Americans, we can use the information from the Pew Research poll. According to the poll, approximately 68% of Americans own a smartphone.

To find the average number of smartphone owners in a sample of 11 Americans, we can multiply the percentage of smartphone owners by 11:

Average number of smartphone owners = 68% x 11 = 7.48

Since we can't have a fraction of a person, we can round up our result to the nearest whole number:

Average number of smartphone owners = 8
