Marketers are interested in the phenomenon of "regifting"-that is, recycling unwanted gifts. For each of the following situations, tell which of these is the focus: data production, displaying and summarizing data, probability, or statistical inference.
a. We'll assume that a certain percentage of Americans recycle gifts. If we consider the likelihood of sample percentage being below a certain value for a sample of a given size, then the focus is on which of the four processes?
b. If we want to use information from a sample survey to draw conclusions about gift recycling habits of all Americans, then the focus is on which of the four processes?
c. Based on results from a survey about regifting, a reporter considers whether to use two pie charts or a single bar graph to compare habits of men and women. Which of the four processes is the focus at this stage?
d. To discover how common gift recycling is, a survey question must be worded carefully to elicit honest and accurate responses. Which of the four processes is the focus at this stage?
