In each of Exercises, we have given a likely range for the observed value of a sample proportion p.

a.Based on the given range, identify the educated guess that should be used for the observed value of ˆ p to calculate the required sample size for a prescribed confidence level and margin of error.
b.Identify the observed values of the sample proportion that will yield a larger margin of error than the one specified if the educated guess is used for the sample-size computation.
