Question

22. The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Upper H 0 when the level of significance is (a) alphaequals0.01, (b) alphaequals0.05, and (c) alphaequals0.10. Pequals0.0368 (a) Do you reject or fail to reject Upper H 0 at the 0.01 level of significance? A. Fail to reject Upper H 0 because the P-value, 0.0368, is less than alphaequals0.01. B. Reject Upper H 0 because the P-value, 0.0368, is greater than alphaequals0.01. C. Fail to reject Upper H 0 because the P-value, 0.0368, is greater than alphaequals0.01. D. Reject Upper H 0 because the P-value, 0.0368, is less than alphaequals0.01.

Answer #1

The P-value for hypothesis test is shown. Use the
P-value to decide whether to reject Ho when the level of
significance is (a) a=0.01, (b) a=0.05, (c) a=0.10.
p=0.0646

Conduct a test at the alphaequals0.10 level of significance by
determining (a) the null and alternative hypotheses, (b) the
test statistic, and (c) the P-value. Assume the samples were
obtained independently from a large population using simple random
sampling. Test whether p 1 greater than p 2. The sample data are x

A genetic experiment involving peas yielded one sample of
offspring consisting of 438 green peas and 161 yellow peas. Use a
0.01 significance level to test the claim that under the same
circumstances, 24% of offspring peas will be yellow. Identify the
null hypothesis, alternative hypothesis, test statistic,
P-value, conclusion about the null hypothesis, and final
conclusion that addresses the original claim. Use the P-value
method and the normal distribution as an approximation to the
binomial distribution.
