Use the information given to find the appropriate minimum sample sizes. (Round your answer up to the nearest whole number.) Estimating P, -p, to within 0.06 with probability 0.98. Assume that the sample sizes will be equal, but that you have no prior knowledge about the values of P, and Pz: n = 1 ₂ 3 You may need to use the appropriate appendix table or technology to answer this question.
