In trying to estimate the variability in the population in order to determine pq,which of the following represents viable alternatives?
A)Use a random number generator to provide two random values for p and q.
B)Use the most conservative approach,p = 10,q = 90.
C)Use 90/10 or find a former study and calculate the variance or conduct a pilot study.
D)Use 1/5 or find a former study and calculate the variance or conduct a pilot study.
E)Use 50/50 or find a former study and calculate the variance or conduct a pilot study.

Using 50/50 is the most conservative approach for estimating variability in a population because it maximizes the product pq, which is used in sample size calculations. Alternatively, finding a former study or conducting a pilot study can provide more accurate estimates of p and q.
