p3 In a large clinical trial, 399,935 children were randomly assigned to two groups. The treatment group consisted of198,188 children given a vaccine for a certain disease, and 27 of those children developed the disease. The other201,747 children were given a placebo, and 83 of those children developed the disease. Consider the vaccinetreatment group to be the first sample. Complete parts (a) through (d) below.a. Assume that a 0.01 significance level will be used to test the claim that p, b. In general, when dealing with inferences for two population proportions, which two of the following are equivalent:confidence interval method; P-value method; critical value method?P-value method and critical value methodare equivalent, in that they will always lead to the sameconclusion. Both of these methods use a standard deviation based onthe assumption that the two population proportions are equal, whereas the other method uses a standarddeviation based on estimated values of the population proportions.c. If a 0.05 significance level is to be used to test the claim that p,
