In a large clinical trial, 400 comma 700 children were randomly assigned to two groups. The treatment group consisted of 199 comma 986 children given a vaccine for a certain disease, and 35 of those children developed the disease. The other 200 comma 714 children were given a placebo, and 105 of those children developed the disease. Consider the vaccine treatment group to be the first sample.
Identify the values of n 1, ModifyingAbove p with caret 1, ModifyingAbove q with caret 1, n 2, ModifyingAbove p with caret 2, ModifyingAbove q with caret 2, p overbar, and q overbar.

In the largest clinical trial ever conducted, 401,974 children
were randomly assigned to two groups. The treatment group consisted
of 201,229 children given the Salk vaccine for polio, and the
other 200,745 children were given a placebo. Among those in the
treatment group, 33 developed polio, and among those in the
placebo group, 115 developed polio. If we want to use the methods
for testing a claim about two population proportions to test the
claim that the rate of polio...

A sample obese adult males were randomly divided into two groups
in a clinical program. In the experimental group, participants were
involved in a vigorous 30-minute-per-day exercise program and also
given instructions on the importance of diet. The control group
only received the diet instructions. The program directors want to
determine if the exercise program had an impact on LDL cholesterol
levels. Below are the LDL cholesterol data after one month in the
program. What can be concluded with an...

12 subjects in a study were randomly assigned into two
equally sized groups. One group was shown a short video on how to
fold paper cranes. The other group was given an instruction booklet
on how to do so. They were then asked to make paper cranes for the
next hour. The number of paper cranes each subject made was
recorded and is listed in the table below. The researchers are
interested in whether there was a difference in the...
