Question
Transcribed Image Text:Two different simple random samples are drawn from two different populations. The first sample consists of 20 people with 9 having a common attribute. The second sample consists of 2200 people with 1598 of them having the same common attribute. Compare the results from
a hypothesis test of P₁ P₂ (with a 0.01 significance level) and a 99% confidence interval estimate of P₁ -P₂-
What are the null and alternative hypotheses for the hypothesis test?
OA. Ho: P₁ P₂
H₁: P1 P2
O D. Ho: P₁ = P₂
H₁: P₁>P2
Identify the test statistic.
(Round to two decimal places as needed.)
Identify the critical value(s).
(Round to three decimal places as needed. Use a comma to separate answers as needed.)
What is the conclusion based on the hypothesis test?
The test statistic is
the critical region, so
The 99% confidence interval is < (P₁-P₂) <L
(Round to three decimal places as needed.)
What is the conclusion based on the confidence interval?
Since 0 is
the null hypothesis.
How do the results from the hypothesis test and the confidence interval compare?
The results are
since the hypothesis test suggests that p₁
in the interval, it indicates to
the null hypothesis. There is
O B. Ho: P₁ = P₂2
H₁: P₁ #P2
O E. Ho: P₁ = P₂2
H₁: P₁ <P2
evidence to conclude that p₁ # P2-
and the confidence interval suggests that p₁
P2-
OC. Ho: P₁ P₂
H₁: P₁ P2
OF. Ho: P₁ P₂
H₁: P₁ = P2
