Two different simple random samples are drawn from two different populations. The first sample consists of 40 people with 19 having a common attribute. The second sampl consists of 2000 people with 1460 of them having the same common attribute. Compare the results from a hypothesis test of p, = P2 (with a 0.05 significance level) and a 95 confidence interval estimate of p, - P2. What are the null and alternative hypotheses for the hypothesis test?

Two different simple random samples are drawn from two different populations. The first sample consists of 40 people with 19 having a common attribute. The second sample
consists of 2000 people with 1460 of them having the same common attribute. Compare the results from a hypothesis test of p, = p2 (with a 0.05 significance level) and a 95%
confidence interval estimate of p, - P2.
What are the null and alternative hypotheses for the hypothesis test?
A. Ho: P1 = P2
В. Но: Р1 - Р2
C. Ho: P1 SP2
H1:P1 <P2
H1: P1 #P2
H1: P1 # P2
O D. Ho: P1 2 P2
H4:P1 #P2
O E. Ho: P1 # P2
H1: P1 = P2
O F. 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 null hypothesis. There is
evidence to conclude that p, # p2.
The 95% confidence interval is
(Round to three decimal places as needed.)

The 95% confidence interval is < (P1 - P2) <U
(Round to three decimal places as needed.)
What is the conclusion based on the confidence interval?
Since 0 is
in the interval, it indicates to
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
P2, and the confidence interval suggests that
P1
P2
