The answer is 21 7/8.
The quantity of the paper needed is the area of parallelogram with a height 3 1/2 and base 6 1/4. The area of a parallelogram (A) is the product of its height (h) and base (b):
A = h * b
We have:
Thus, the area of paralleogram is:

Using the z-distribution, the sample sizes are given as follows:
a) 822.
b) 1068.
<h3>What is a confidence interval of proportions?</h3>A confidence interval of proportions is given by:
In which:
is the sample proportion.
- z is the critical value.
- n is the sample size.
The margin of error is given by:
In this problem, we have a 95% confidence level, hence, z is the value of Z that has a p-value of
, so the critical value is z = 1.96.
Item a:
The estimate is of , hence we solve for n when M = 0.03.
n = 821.2
Rounding up, a sample of 822 is needed.
Item b:
No prior estimate, hence .
n = 1067.11
Rounding up, a sample of 1068 is needed.
