(Round your answers to two decimal places.) Z0.85 m = Compute the sample size n for estimating the proportion p of all people who have blood type B under these restrictions. (Round your answer up to the nearest whole number.) n = medical files (b) Answer part (a) if you use the preliminary estimate that about 15 out of 90 people have blood type B. (Round your proportions to three decimal places and your sample size up to the nearest whole number.) 1 -p = n = medical files Need Help? Read It Watch It
