- If a payoff is equally likely to be $1, $2, $3, $4, or $5, the coefficient of variation is: Group of answer choicesShould large retailers offer banking services? Small community banks may be concerned about their future if more retailers enter the world of banking. Suppose that a market research company conducted a national survey for one retailer that is considering offering banking services to its customers. The respondents were asked to indicate the provider (bank, retail store, other) that they most likely would use for certain banking services (assuming that rate is not a factor). Is there a relationship between these two variables?

- A student wondered what proportion of a large jar of thousands of marbles were red and speculated that it was 0.30. She took a random sample of 50 marbles and got 18 red marbles, for a sample proportion of 0.36. Below is a dotplot of 100 simulated samples of drawing 50 marbles from a population that is set up to have the proportion of "red marbles" to be 0.30. Based on this dotplot, would getting a sample of 50 marbles to have a 0.36 proportion of red marbles be significant evidence that the true proportion of red marbles in the whole jar is greater than 0.30?A health researcher studying child birth is interested in the possible effect that smoking by the mother during pregnancy has on the baby's birth weight. To investigate, the researcher conducts an observational study by reviewing 400 records of women in their twenties who have recently given birth for the first time. For each record, he notes whether or not the woman smoked during pregnancy and the baby's birth weight, in addition to the woman's education level, and age. From the data, the researcher creates two groups: women in their twenties who smoked during pregnancy and women in their twenties who did not smoke during pregnancy. Then he compares the average birth weight between the two groups. (a)Why might the researcher have chosen to perform an observational study (by gathering information from past records) and not a randomized experiment (by assigning pregnant women to either the smoking or nonsmoking group at random)? Choose the best answer from the choices below. In a…Chapter 4, Section 2, Exercise 065 Finger Tapping and CaffeineThe effects of caffeine on the body have been extensively studied. In one experiment1, researchers examined whether caffeine increases the rate at which people are able to tap their fingers. Twenty students were randomly divided into two groups of 10 students each, with one group receiving caffeinated coffee and one group receiving decaffeinated coffee. The study was double-blind, and after a 2-hour period, each student was tested to measure finger tapping rate (taps per minute). The goal of the experiment was to determine whether caffeine produces an increase in the average tap rate. The finger-tapping rates measured in this experiment are stored in CaffeineTaps. A distribution of differences in means, x¯c-x¯n, for randomization samples from this experiment is given in the figure below.Let group 1 be the people who have had coffee with caffeine and let group 2 be the people who have had coffee without caffeine.…
- How will marketers change their social media use in the near future? A survey by Social Media Examiner reported that 77% of B2B marketers (marketers that focus primarily on attracting businesses) plan to increase their use of LinkedIn, as compared to 54% of B2C marketers (marketers that primarily target consumers). The survey was based on 1,184 B2B marketers and 1,703 B2C marketers. The following table summarizes the results: Give an example of a simple Give an example of a joint What is the complement of a marketer who plans to increase use of LinkedIn? Why is a marketer who plans to increase use of LinkedIn and is a B2C marketer a joint event?In the Focus Problem at the beginning of this chapter, a study was described comparing the hatch ratios of wood duck nesting boxes. Group I nesting boxes were well separated from each other and well hidden by available brush. There were a total of 463 eggs in group I boxes, of which a field count showed about 280 hatched. Group II nesting boxes were placed in highly visible locations and grouped closely together. There were a total of 812 eggs in group II boxes, of which a field count showed about 274 hatched.
