In a large clinical​ trial, 400,765 children were randomly
assigned to two groups. The treatment group consisted of 202,098
children given a vaccine for a certain​ disease, and 29 of those
children developed the disease. The other 198,667 children were
given a​ placebo, and 108 of those children developed the disease.
Consider the vaccine treatment group to be the first sample.
Identify the values of n1​, p1​, q1​, n2​, p2​, q2​, p​, and q.
A newspaper published an article about a study in which
researchers subjected laboratory gloves to stress. Among 292
vinyl​ gloves, 56​% leaked viruses. Among 292
latex​ gloves, 9​% leaked viruses. Using the accompanying
display of the technology​ results, and using a 0.05
significance​ level, test the claim that vinyl gloves have a
greater virus leak rate than latex gloves. Let vinyl gloves be
population 1.
Identify the test statistic.
Identify the​ P-value.
What is the conclusion for this​ test?
