Question

1) Find n for a 99% confidence interval for p with bound on the error of estimation (margin of error) = 0.03 using an estimate of p = 0.85. (Round up to the nearest whole number.)

2)Find the conservatively large value for n using the same confidence interval and bound on the error of estimation (margin of error) mentioned in part a with no estimate of p. (Round up to the nearest whole number.)
