CASE PROBLEM: TOURISTOPIA TRAVEL
TourisTopia Travel (Triple T) is an online travel agency that specializes in trips to ex-
otic locations around the world for groups of ten or more travelers. Triple T’s marketing manager has been working on a major revision of the homepage of Triple T’s website.
The content for the homepage has been selected and the only remaining decisions involve the selection of the background color (white, green, or pink) and the type of font (Arial,Calibri, or Tahoma).
Triple T’s IT group has designed prototype homepages featuring every combination of
these background colors and fonts, and it has implemented computer code that will randomly direct each Triple T website visitor to one of these prototype homepages. For three weeks, the prototype homepage to which each visitor was directed and the amount of time in seconds spent at Triple T’s website during each visit were recorded. Ten visitors to each of the prototype homepages were then selected randomly; the complete data set for these visitors is available in the file TourisTopia.
Triple T wants to use these data to determine if the time spent by visitors to Triple T’s
website differs by background color or font. It would also like to know if the time spent by visitors to the Triple T website differs by different combinations of background color and font.
Managerial Report

Based on descriptive statistics, what are your preliminary conclusions about whether the time spent by visitors to the Triple T website differs by background color or font? What are your preliminary conclusions about whether time spent by visitors to the Triple T website differs by different combinations of background color and font?
