television set, 83% had two or more sets. A local cable company canvassing the town to promote a new cable service
found that of the 295 households visited, 241 had two or more television sets. At a= 0.05, is there sufficient evidence to

Sample Question
Television Set Ownership According to Nielsen Media Research, of all the U.S. households that owned at least one
television set, 83% had two or more sets. A local cable company canvassing the town to promote a new cable
service found that of the 295 households visited, 234 had two or more television sets. At a = 0.01, is there sufficient
evidence to conclude that the proportion is less than the one in the report? Do not round intermediate steps.
(a) State the hypotheses and identify the claim.
(b) Find the critical value.
(c) Compute the test value.
(d) Make the decision.
(e) Summarize the results.
Explanation
(a) State the hypotheses and identify the claim.
The null hypothesis H, is the statement that there is no difference between a parameter and a specific value. This is
equivalent to p= 0.83.
The alternative hypothesis H is the statement that there is a difference between a parameter and a specific value.
In this case, the proportion is less than the one in the report. This is equivalent to p< 0.83.
The problem asks, "Is there sufficient evidence to conclude that the proportion is less than the one in the report?"
Hence, the claim is the alternative hypothesis H.
(b) Find the critical value.
From the figure, for a left-tailed test with a=0.01, the critical value is z=-2.33.

H, :u#k
a=0.01, C.V.=+2.58
(c) Two-tailed
(c) Compute the test value.
First, it is necessary to find p, p, and q.

Geographer louie intends to investigate whether there is a difference in how happy tourists are with their journey depending on where they are in the country (which part of the country). He divided the country into 5 parts: capital, south, east, west og north and selected 30 tourists at random from each area and asked (e. Chose 30 tourists in each part) and asked, "how enjoyable has your journey been in these areas on a scale of 0-10". louie is happy to have taken statistics in his time because there he learned to analyze data of this kind with analysis of variance. He started filling out an ANOVA table but could not complete it. The table can be seen below. It can be assumed that satisfaction follows a normal distribution and the distribution is similar in the five areas (e.
