K Do cars get better gas mileage with premium instead of regular unleaded gasoline? It might be possible to test some engines in a laboratory, but we'd rather use real cars and real drivers in real day-to-day driving, so we get 20 volunteers. Design the experiment. ... Determine how the experiment should be carried out. Choose the correct answer below. OA. Have each volunteer use different kinds of gas depending on the trip. Use premium for highway and use regular for back roads. B. Have each of the volunteers use each kind of gas for a month. Randomly assign 10 of them to use regular first and the other 10 to use premium first. OC. Have each volunteer only use one kind of gas for the duration of the experiment. Assign 10 to only use regular and 10 to only use premium. OD. Have 10 of the volunteers not drive their cars and have the remaining 10 volunteers use different types of gasoline, on various roads. Identify the factors, levels, and variables of the experiment. This experiment…
6. Flu Season The pie chart shown, the type we see in USA Today, depicts the approaches people use to avoid getting the flu. How to Beat the Flu Bug In a recent survey by Kiwanis International and Novartis Vaccines, people were asked, "What do you think is the best way to protect against the flu?" The results: Washing your hands (61%) Getting a flu shot (25%) Taking vitamins (12%) Drinking orange juice (2%) Source: Kiwanis International and Novartis Vaccines. (a) What is the most common approach? What percentage of the population chooses this method? (b) What is the least used approach? What percentage of the population chooses this method? (c) What percentage of the population thinks flu shots are the best way to beat the flu?
O Macmillan Learning A randomly sampled group of patients at a major U.S. regional hospital became part of a nutrition study on dietary habits. Part of the study consisted of a 50-question survey asking about types of foods consumed. Each question was scored on a scale from one: most unhealthy behavior, to five: most healthy behavior. The answers were summed and averaged. The population of interest is the patients at the regional hospital. A prior study conducted at the hospital showed that averaging scores over 50 questions produces a Normal population distribution. If we obtain a sample of n = 15 subjects and wish to calculate a 95% confidence interval, the critical value t* is: O 1.753. O2.145. O 1.761. O 2.131.
Hypothesis testing with One Way ANOVA. Use hypothesis testing to answer the research questions, labeling each step and completing any post-tests. Researchers want to know if surroundings make a difference in ability to remember a list of words. They test this by randomly assigning subjects to three conditions: shopping mall setting, driving in a car setting (simulation) and in an outdoor setting. Here are the memory scores for each condition: Mall Condition Driving Condition Outdoor Condition 8 8 15 7 7 10 8 5 12 6 8 9 9 10 14 12 10 10 7 12 8 8 8 10
