Question

The American Heart Association is about to conduct an anti-smoking campaign and wants to know the fraction of Americans over 48 who smoke. Step 1 of 2: Suppose a sample of 271 Americans over 48 is drawn. Of these people, 220 don't smoke. Using the data, estimate the proportion of Americans over 48 who smoke. Enter your answer as a fraction or a decimal number rounded to three decimal places.

Answer 1

0.188

Explanation:

The computation is shown below;

First we have to determine the no of smokers

= Total no of persons - number of non-smokers

= 271 - 220

= 51

Now we have to estimate the proportion

So for this

= 51 ÷ 271

= 0.188192

= 0.188

Hence, the estimation is 0.188

The same is to be considered
