Hotels’ use of ecolabels. Ecolabels such as Energy Star, Green Key, and Audubon International are used by hotels to advertise their energy-saving and conservation policies. The Journal of Vacation Marketing (January 2016) published a study to investigate how familiar travelers are with these ecolabels and whether travelers believe they are credible. A sample of 392 adult travelers were administered a questionnaire. One question showed a list of 6 different ecolabels, and asked, “How familiar are you with this ecolabel, on a scale of 1 (not familiar at all) to 5 (very familiar).” Summarized results for the numerical responses are given in the table.
- a. Give a practical interpretation of the
mean response for Energy Star. - b. Give a practical interpretation of the median response for Energy Star.
- c. Give a practical interpretation of the response
mode for Energy Star. - d. Based on these summary statistics, which ecolabel appears to be most familiar to travelers?
