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?
