Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

If the claim in part (c) is tested using this sample data, we get this confidence interval: -0.000483 < p1 -p 2< - 0.000324

What does this confidence interval suggest about the claim?

In a large clinical trial, 393,577 children were randomly assigned to two groups. The treatment group consisted of 195,930 children given a vaccine for a certain
disease, and 35 of those children developed the disease. The other 197,647 children were given a placebo, and 115 of those children developed the disease. Consider
the vaccine treatment group to be the first sample. Complete parts (a) through (d) below.
deviation based on the assumption that the two population proportions are equal, whereas the other method uses a standard deviation based on
estimated values of the population proportions.
c. If a 0.10 significance level is to be used to test the claim that p, <p,, what confidence level should be used?
80'%
(Type an integer or a decimal.)
d. If the claim in part (c) is tested using this sample data, we get this confidence interval: -0.000483 <p, - p, < - 0.000324. 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
it appears that the first proportion
is
V the second proportion. There is
evidence to support the claim that the rate of polio is less for children given the
vaccine than it is for children given a placebo.
