In a large clinical trial, 392,327 children were randomly assigned to two groups. The treatment group consisted of 196,551
children given a vaccine for a certain disease, and 35 of those children developed the disease. The other 195,776 children were
given a placebo, and 133 of those children developed the disease. Consider the vaccine treatment group to be the first sample.
Complete parts (a) through (d) below.
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
whereas the other method uses a standard deviation based on
c. If a 0.01 significance level is to be used to test the claim that p, <p2, what confidence level should be used?
%
(Type an integer or a decimal.)
d. If the claim in part (c) is tested using this sample data, we get this confidence interval: - 0.000655 < p, - P2< - 0.000347.
What does this confidence interval suggest about the claim?
Because the confidence interval
there
a significant
difference between the two proportions. Because the confidence interval consists
V it appears that the first proportion is
V the second proportion.
