4.98 HOTELS' USE OF ECOLABELS. Refer to the Journal of Vacation Marketing (January 2016) study of travelers' familiarity with ecolabels used by hotels, Exercise 2.640 (p. 79). Recall that adult travelers were shown 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)." The mean and standard deviation of the responses for the Energy Star ecolabel are 4.44 and .82, respectively. Assume the distribution of the responses is approximately normally distributed. a. Find the probability that a response to Energy Star exceeds 4. b. Find the probability that a response to Energy Star falls between 2 and 4. NW c. If you observe a response of 1 to an ecolabel, do you think it is likely that the ecolabel shown was Energy Star? Explain.
