If we are using the formula for calculating the sample size for estimating a percentage, the formula will contain:
A) s
B) %
C) Z³
D) pq
E) N

Question

Quizplus · Accepted Answer

The formula for calculating the sample size for estimating a percentage is:

n = (Z² * pq) / E²

where: 
- n = sample size 
- Z = z-score (corresponding to the desired level of confidence)
- p = estimated proportion or percentage
- q = 1-p
- E = margin of error

Therefore, the formula will contain pq as key variables.
