Question No 9.68
La Quinta Motor Inns developed a computer model to
help predict the profitability of sites that are being considered
as locations for new hotels. If the computer model predicts
large profits, La Quinta buys the proposed site and
builds a new hotel. I f the computer model predicts small or
moderate profits, La Quinta chooses not to proceed with
that site (data extracted from S. E. Kimes and 1. A.
Fitzsimmons, “Selecting Profitable Hotel Sites at La Quinta
Motor Inns,” Interfaces, Vol. 20, March•-April 1990.
pp. 12-20). This decision-making procedure can be expressed
in the hypothesis-testing framework. The null hypothesis is
that the site is not a profitable location. The alternative
hypothesis is that the site is a profitable location.
