Answer:
n = 1537 represent the sample size of American over 46
X = 1537-1245=292 represent the number of Americans over 46 who smoke
And for this case in order to estimate the population proportion we can use this formula:
[tex]\hat p = \frac{X}{n}[/tex]
Where:
X represent the number of people with the characteristic desired and n the sample size. If we replace we got:
[tex]\hat p = \frac{292}{1537}= 0.190[/tex]
Step-by-step explanation:
For this case we deine the parameter of interest p as the proportion of Americans over 46 who smoke.
We know the following info provided:
1245 people don't smoke
n = 1537 represent the sample size of American over 46
X = 1537-1245=292 represent the number of Americans over 46 who smoke
And for this case in order to estimate the population proportion we can use this formula:
[tex]\hat p = \frac{X}{n}[/tex]
Where:
X represent the number of people with the characteristic desired and n the sample size. If we replace we got:
[tex]\hat p = \frac{292}{1537}= 0.190[/tex]
