Answer:
We must survey at least 48 people from this younger age group.
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 .
The margin of error is:
90% confidence level
So , z is the value of Z that has a pvalue of , so .
How many of this younger age group must we survey in order to estimate the proportion of non-grads to within .10 with 90% confidence? Use the value of p from the over-50 age group.
This is n when
So
Rouding up,
We must survey at least 48 people from this younger age group.

If they didn’t want you to find the very final product like the ones I showed on top here are simpler forms
22) 84 to the power of 6 (84^6)
24) 45 to the power of 4 (45^4)
30) 46^4
