In a large clinical trial, children were randomly assigned to two groups. The treatment group consisted of children given a vaccine for a certain disease, and of those children developed the disease. The other children were given a placebo, and of those children developed the disease. Consider the vaccine treatment group to be the first sample. Complete parts (a) through (d) below. a. Assume that a significance level will be used to test the claim that . Which is better: A hypothesis test or a confidence interval? A hypothesis test is better. 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? ▼ are equivalent, in that they will always lead to the same conclusion. Both of these methods use a standard deviation based on ▼ estimated values of the population proportions, the assumption that the two population proportions are equal, whereas the other method uses a standard deviation based on ▼ the assumption that the two population proportions are equal. estimated values of the population proportions.
