In 2005, Health Canada claimed that 16.9% of Canadian adults are obese. A researcher wanted to check whether this percentage has changed in 2009. In 2009, he randomly selected 90 Canadian adults and found 12 of them are obese. Use a 7% significance level. The decision rule is either Reject Ho if Zcalc > 1.48 Reject Ho if Zcalc > 1.81 Reject H0 if Zcalc < -1.81 or Zcalc > 1.81 Reject H0 if Zcalc < -1.48 or Zcalc > 1.48
A classic story involves four carpooling students who missed a test and gave as an excuse a flat tire. On the makeup test, the instructor asked the students to identify the particular tire that went flat. If they really didn't have a flat tire, would they be able to identify the same tire? A statistician asked 47 other randomly selected students to identify the tire they would select. The results are listed in the accompanying table. Use a 0.05 significance level to test the statistician's claim that the results fit a uniform distribution. What does the result suggest about the likelihood of four students identifying the same tire when they really didn't have a flat? Tire Number Selected Left Front 12 Right Front 8 ...

A company that produces a particular brand of juice knows that about 30% of people select that brand if given a choice of all brands. To determine if a commercial would be an effective advertising tool, the company invites 100 people to view a 30-minute program that includes a commercial for the company’s juice. After the program, the participants are offered a choice of juice brands. In this trial, 36 of the 100 participants chose the company’s juice. When a significance test was performed to determine if the true proportion of people who watch the commercial and select the company’s juice exceeds 30%, the P-value was 0.0952. At the α = 0.05 significance level, what decision should the company make? A. Because the P-value of 0.0952 > α = 0.05, the company has evidence that the true proportion of those who would select the company’s juice is larger than 30%. B. Because the P-value of 0.0952 < 0.3, the company has evidence that the true proportion of those who would select the…

Suppose that you wanted to buy a new Honda Civic and you want to wait until you can get a good deal. You want to see if the usual/average price of a Honda Civic is below the blue book value of $21,550. You are unsure that the prices of the current listings around you are lower than the blue book value of a Honda Civic so you randomly sample 49 listings from the area and find their sample mean selling price is $20,015 and their sample standard deviation is $1750.
Among 5,000 items of randomly selected baggage handled by American Airlines, 20 were lost. Among 4,000 items of randomly selected baggage handled by Delta Airlines, 18 were lost.
