Question

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.

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).

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.

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.

5) Identify the null hypothesis, alternative hypothesis, test
statistic, critical value(s), conclusion about the null hypothesis,
and final conclusion that addresses the original claim.
In a 3M Privacy Filters poll, 806 adults were asked to identify
their favorite seat when they fly, and 492 of them chose a window
seat. Use 0.01 significance level to test the claim that 62% of
adults prefer window seats when they fly.

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
cars....

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 survey of 1025
adults found that 113 of them, or 11%, said they or a household
member had been a victim of a computer or internet crime on their
home computer in the past year. At the 0.05 level of significance,
test the claim that the rate of internet crime victims is less than
12%.

Identify the null hypothesis, alternative hypothesis, test
statistic, P-value, conclusion about the null hypothesis, and final
conclusion that addresses the original claim. The health of
employees is monitored by periodically weighing them in. A sample
of 54 employees has a mean weight of 183.9 lb. Assuming that ? is
known to be 121.2 lb, use a 0.10 significance level to test the
claim that the population mean of all such employees weights is
less than 200 lb.

Identify the null hypothesis, alternative hypothesis, test
statistic, P-value, conclusion about the null hypothesis, and final
conclusion that addresses the original claim. Assume that you plan
to use a significance level of ? = 0.05 to test the claim that ?1 =
?2. A report on the nightly news broadcast stated that 10 out of
145 households with pet dogs were burglarized and 23 out of 187
without pet dogs were burglarized.
