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.

Find using traditional method or P-value method. Identify the null
and alternative hypothesis, test statistic, critical value(s) or
P=value (or range of P-values) as appropriate, and state the final
conclusion that addresses the original claim.
A company claims that the mean weight of the oatmeal in its
packets is 14oz. The weights in ounces of the oats in a random
sample of 8 of the oat packets are listed below

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 20142014
passenger cars in a particular region, 226226 had only rear
license plates. Among 306306 commercial trucks, 4747 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....
