Estimate p, the proportion in favour of the new office branch and place a bound on the error of estimation. (a) (b) Determine the sample size required to estimate p with a bound on the error of estimation of magnitude B = 0.01. (c) Do you think that the sample size is suitable for the population? Explain your answer.
