In a large clinical trial, 400,674 children were randomly assigned to two groups. The treatment group consisted of 200,196 children given a vaccine for a certain disease, and 36 of those children developed the disease. The other 200,478 children were given a placebo, and 123 of those children developed the disease. Consider the vaccine treatment group to be the first sample. Identify the values of n,. P1. 91. n2. P2. 92. p, and q. n, = 200,196 (Type an integer or a decimal rounded to eight decimal places as needed.)
