To see if police are more likely to pull over certain color cars, researchers gathered 28 Volkswagen Jettas and had them painted one of four colors: red, grey, black, and white. Participants drove the cars around for a month and recorded the number of traffic stops that occurred for each color. The results are below.

∑X² = 2030

Red Cars: M = 12, T = 84, SS = 70, n = 7

Grey Cars: M = 4, T = 28, SS = 35, n = 7

Black Cars: M = 8, T = 56, SS = 63, n = 7

White Cars: M = 6, T = 42, SS = 42, n = 7

1.Specify the null and alternative hypotheses that car color affected the number of traffic stops.

2. Report the SS-Total, the SS-Within, and the SS-Between of an ANOVA

3. Report the MS-Within, the MS-Between, and the F-ratio of an ANOVA.

4. Using alpha = .01, report your decision about the impact of car color on traffic stops.

Researchers for an advertising company are interested in determining if people are more likely to spend more money on beer if advertisers put more beer ads on billboards in a neighborhood in Philadelphia. They estimate that 250 people will view their billboard in one week. They determine that the total number of residents in the neighborhood is 600. So, the residents who have not viewed the billboard are in the control group. The researchers determine that those who did view...

A regulatory agency suspected that more than 10% of all cars of a certain automobile model are unsafe. A random sample of 16 cars finds that 6 of these sampled cars are unsafe. (a) Test the appropriate hypotheses, keeping the significance level at no more than 0.05. Give your decision rule, test statistic value, p-value, and conclusion. (b) What is a 90% confidence interval for the true proportion of unsafe cars in the population?

Researchers suspect that myopia, or nearsightedness, is becoming more common over time. A study from the year 2010 showed 123 cases of myopia in 400 randomly selected people. Another study from the year 2019 showed 228 cases in 600 randomly selected people. We are going to do a hypothesis test to see if p1 = the proportion of people who have myopia in 2019 is equal to p2 = proportion of people who have myopia in 2010 at the 0.05 significance...

Word-of-mouth communications can be very persuasive. You’re more likely to see a movie or buy a clothing brand because your friends recommended them. This is viral marketing. However, marketers are harnessing the power of viral marketing with creative tactics. So called ‘stealth marketing’ are criticized because consumers don’t know they are being marketed to. For example, Sony Ericsson came under fire when it became known that it hired actors to pose as tourists asking strangers to take their picture with...
