Question
For one binomial experiment,
successes. For a second independent binomial experiment,
nz = 100 binomial trials produced 2=70 successes. At the 5% level of
significance, test the claim that the probabilities of success
for the two binomial experiments differ.
m = 75 binomial trials produced ,
n = 45
(a) Compute the pooled probability of success for the two
experiments. (Round your answer to three decimal places.)
0.657
(b) Check Requirements: What distribution does the
sample test statistic follow? Explain.
The Student's t. The number of trials is sufficiently large.
The standard normal. We assume the population distributions are approximately normal.
The Student's t. We assume the population distributions are approximately normal.
The standard normal. The number of trials is sufficiently large.
(c) State the hypotheses.
Ho: P1 = P2; H1: P1 > P2
• Ho: P1 = P2; H:P1 * P2
Ho: P1 = P2; H1: P1 < P2
Ho: P1 < P2; H1: P1 = P2
