Answer:
The 99% confidence interval estimate for the proportion of all 17-year-old students in 2012 who had at least one parent graduate from college is (0.4964, 0.5236).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
Sample of 9000, 51% of students had at least one parent who was a college graduate.
This means that 
99% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 99% confidence interval estimate for the proportion of all 17-year-old students in 2012 who had at least one parent graduate from college is (0.4964, 0.5236).

<span>The goal in simplifying numbers
is to reduce it that can be best seen in the eye. Also in
converting units, you must take note of the units given in the problem. If you
don’t, you would get a lot of errors. Length is the measure of distance and can
be best represented by either in SI units or English units. Example of an SI unit is meter, m, and English
unit is feet, ft. You are given 3 inches and 2 feet. You can convert any of the
numbers into a number that would feel comfortable to you. I will take 3 inches.
Note that there are 12 inches in 1 feet. So divide 3 by 12 and you will get ¼ feet.
Then divide 2 feet to ¼ feet and you will get 8.</span>
