Answer #1

Identify the null and alternative hypothesis(in symbolic and
sentence form), test statistic, P-value(or critical values),
conclusion about the null hypothesis, and final conclusion that
addresses the original claim (Don’t just say Reject the null
hypothesis or fail to reject the null hypothesis).

subjects reported experiencing significant relief from their
symptoms. At the 0.01 significance level, test the claim that more

Identify the following. Show your work. a) null hypothesis,
alternative hypothesis, b) test statistic, c) P-value or critical
value(s) d) conclusion about the null hypothesis, and final
conclusion that addresses the original claim. In a clinical study
of an allergy drug, 108 of the 202 subjects reported experiencing
significant relief from their symptoms. At the 0.01 significance
level, test the claim that more than half of all those using the
drug experience relief.

In
a clinical study of an allergy drug, 98 of the 202 subjects
reported experiencing significant relief from their symptoms. At
the 0.01 significance level, test the claim that at least half of
all those using the drug experience relief.

Identify the null hypothesis, alternative hypothesis, test
statistic, P-value, conclusion about the null hypothesis, and final
conclusion that addresses the original claim. Test the claim that
the mean lifetime of car engines of a particular type is greater
than 220,000 miles. Sample data are summarized as n = 23, ?̅ =
226,450 miles, and s = 11,500 miles. Use a significance level of ?
= 0.01.

Test the given claim. Identify the null? hypothesis, alternative?
hypothesis, test? statistic, P-value, and then state the conclusion
about the null? hypothesis, as well as the final conclusion that
addresses the original claim. Among 2197 passenger cars in a
particular? region, 256 had only rear license plates. Among 346
commercial? trucks, 53 had only rear license plates. A reasonable
hypothesis is that commercial trucks owners violate laws requiring
front license plates at a higher rate than owners of passenger
cars....

Identify the null hypothesis, alternative hypothesis,
test statistic, P-value, conclusion about the null hypothesis, and
final conclusion that addresses the original claim.
A manufacturer considers his production process to be out of
control when defects exceed 3%. In a random sample of 85 items, the
defect rate is 5.9% but the manager claims that this is only a
sample fluctuation and production is not really out of control. At
the 0.01 level of significance, test the manager's claim.

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.
A study was done on body temperatures of men and women. Here are
the sample statistics for the men: x1 = 97.55oF, s1 = 0.83oF, n1 =
11, and for the women: x2 = 97.31oF, s2 = 0.65oF, n2 = 59. Use a
0.06 significance level to test the claim that µ1 > µ2.

Assume that a simple random sample has been selected and test
the given claim. Identify the null and alternative hypotheses,
test statistic, P-value, and state the final conclusion that
addresses the original claim. Listed below are brain volumes in
cubedcm3 of unrelated subjects used in a study. Use a 0.01
significance level to test the claim that the population of brain
volumes has a mean equal to 1100.3 cubedcm3.

Test the given claim. Identify the null hypothesis, alternative
hypothesis, test statistic, P-value, and then state the conclusion
about the null hypothesis, as well as the final conclusion that
addresses the original claim. Among 2148 passenger cars in a
particular region, 231 had only rear license plates. Among 347
commercial trucks, 48 had only rear license plates. A reasonable
hypothesis is that commercial trucks owners violate laws requiring
front license plates at a higher rate than owners of passenger

Test the given claim. Identify the null hypothesis,
alternative hypothesis, test statistic, P-value, and then state
the conclusion about the null hypothesis, as well as the final
conclusion that addresses the original claim. Among 2064 passenger
cars in a particular region, 227 had only rear license plates.
Among 364 commercial trucks, 51 had only rear license plates. A
reasonable hypothesis is that commercial trucks owners violate laws
requiring front license plates at a higher rate than owners of
passenger cars....
