TUTORIAL 11 1. A study published in The Journal of American Academy of Business, Cambridge (March 2002) examined whether the perception of service quality at five-star hotels in Jamaica differed by gender. Hotel guests were randomly selected from the lobby and restaurant areas and asked to rate ten service-related items (e.g., "The personal attention you received from our employees"). Each item was rated on a 5-point scale (1 = "much worse than I expected," 5 = "much better than I expected") and the sum of the items for each guest was determined. A summary of the guest scores are provided in the next table. Gender Sample Size Mean Score Standard Deviation Males 127 Females 114 39.08 38.79 6.73 6.94 a. Construct a 90% confidence interval for the difference between the population mean service- rating scores given by male and female guests at Jamaican five-star hotels. b. Use the interval, part a, to make an inference about whether the perception of service quality at five-star hotels in Jamaica differs by gender.
