Means compplete the square on one side
basically get into form
ok, group x terms
factor out linear coefient (-8)
take 1/2 of the linear coefient and square it
8/2=4, 4^2=16
add positive and negaitve of that inside parntheaese
factor perfect square
expand
in vertex form it is

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:
