Question number 11.
When solving for the sample size required to estimate p to within a particular margin of error, under what circumstances do we use p̂ = .5?
When the variance is equal to .5 or when we desire a most conservative sample size.
When we have no prior information on the approximate value of p̂ or p.
When the margin of error desired is less than or equal to .5
When the computed value of p̂ = .5
When p̂ = .4 and 1 - p̂ = .6
None of the above
