Answer to Problem 18PPS

The sample is not biased and the conclusion is not valid.

Explanation of Solution

Given information:

The Canton repository polled 750 people the result of the people who talked on a cell phone while driving a car is never, 20%; a few times, 48.7%; not anymore, 5.1%; always, 25.5%.

Calculation:

It can be observed that the sample is large enough, reputable and since they are drivers who were chosen randomly so the sample is not biased.

Also, since the highest percentage of responses is a few times and always so the data also supports the conclusion. Hence, the conclusion is valid.

Thus,

The sample is not biased and the conclusion is not valid.
