Question

The American Heart Association is about to conduct an anti-smoking campaign and wants to know the fraction of Americans over 44 who smoke. Step 1 of 2 : Suppose a sample of 2653 Americans over 44 is drawn. Of these people, 2149 don't smoke. Using the data, estimate the proportion of Americans over 44 who smoke. Enter your answer as a fraction or a decimal number rounded to three decimal places.

Answer 1

The proportion of Americans over 44 who smoke is 0.189.

Explanation:

We are given the following in the question:

Sample size, n = 2653

Number of Americans over 44 who does not smoke = 2149

Thus,

Number of Americans over 44 who smoke,x =

`x=2653-2149\\x=504`

We have to estimate the proportion of Americans over 44 who smoke.

Formula:

`\hat{p} = (x)/(n) = (504)/(2653)=0.189`

The proportion of Americans over 44 who smoke is 0.189.
