Part 2: For each hypothesis question (6 - 8): (a) state the
claim mathematically, (b) identify the null and
alternate hypotheses, (c) determine the type of test to be used,
(d) calculate the test statistic, (e) use
either the p-value or critical region method to test the claim, (f)
determine whether to reject or fail to
reject the Null Hypothesis, (g) state your conclusion.
6. Fandango claim’s that the average cost of a movie ticket is
at least $8.75 for an adult, with a known variance of $0.25. To
test this claim, a random sample of 75 tickets had a mean of $8.06.
There is no reason to think the variance is any different in the
sample. Based upon this information, can we reject Fandango’s claim
at the 5% level of significance?

Question 6: In the following: a). Identify the claim and state
H0 and Ha. b). Find critical value(s) and the rejection region(s).
c). Find the standardized test statistic: t-score. d). Decide
whether to reject or fail to reject null hypothesis. e). Interpret
the decision in context of original claim. A magazine claims that

(a) Write the claim mathematically and identify Upper H 0 and
Upper H Subscript a. (b) Find the critical value(s) and identify
the rejection region(s). (c) Find the standardized test
statistic. (d) Decide whether to reject or fail to reject the null
hypothesis. A medical researcher says that at least 24% of adults
are smokers. In a random sample of 160 adults, 22.5% say they are
smokers. At alphaequals0.03, do you have enough evidence to reject
the researcher's claim?

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 2084 passenger
cars in a particular region, 241 had only rear license plates.
Among 349 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....
