question 7

Multiple Choice

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
