A recent study in a marketing journal used a sample gathered by asking individuals to complete an online survey about a particular product. This survey was then used to make inference about the characteristics (e.g., income and education levels) of the buyers of the product.  

If you were reviewing their results, what statistical issues might you want to focus on? What questions might you want to ask the researchers?

A recent study in the Journal of the American Medical Association reported the results of an experiment where 40 overweight individuals followed the Zone diet for one year. Their weight changes at the end of the year had a mean of x¯=3.1x¯=3.1 kg with a standard deviation of s=5.9s=5.9 kg. We want to use this data to test the claim that the diet has an effect, that is, that the weight change is higher than 0. 1. Which set of...

Direct marketing companies are turning to the Internet for new opportunities. A recent study by Gruppo, Levey, & Co. showed that 73% of all direct marketers conduct transactions on the Internet. Suppose a random sample of 310 direct marketing companies is taken. a. What is the probability that between 220 and 241 (inclusive) direct marketing companies are turning to the Internet for new opportunities? b. What is the probability that 75% or more of direct marketing companies are turning to...

In a recent sample of 83 used cars sales costs, the sample mean was $6,425 with a standard deviation of $3,156. Assume the underlying distribution is approximately normal. NOTE: If you are using a Student's t-distribution, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.) a.) Construct a 95% confidence interval for the population mean cost of a used car. b.)(iii) Calculate the error bound. (Round your answer to one...

A recent study in the Journal of Consumer Research suggests that appetite stimuli can make people more impatient in unrelated areas. Participants in the study, all college students, were asked to serve as photo editors for a magazine. Half were randomly selected to view appetite-stimulating pictures of desserts, and the other half viewed non-appetite-stimulating nature pictures. Then the participants were offered a choice between an apartment with a great view and an apartment close to work. The apartment with a...

A study on highway safety studied the driving habits of individuals. A sample of 78 cars travelling on the highway revealed an average speed of 94 kph with a standard deviation of 29.9 kph. Determine the 95% confidence interval for the mean speed of all cars (kph), if it is known that speed is normally distributed. Give the upper limit only (in kph) correct to three decimal places.
