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:

Where:
X represent the number of people with the characteristic desired and n the sample size. If we replace we got:

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:

Where:
X represent the number of people with the characteristic desired and n the sample size. If we replace we got:

Percentage change from 50 to 82, first, let's solve how much is added from 50 to 82.
=> 82 - 50 = 32
Now how many percent is 32 out of 50?
=> 32 / 50 = 0.64
=> 0.64 * 100% = 64%
thus 64% added or increased in the previous number.
