An organizational specialist is hired as a consultant to a company planning to open a coffee house for college students. The company wants to know if the customers will drink more or less coffee if the coffee house is decorated in a Paris motif or in a San Francisco motif. To test this, the researcher sets up two similar rooms, but with the two different motifs. She then arranges to have eight students spend an afternoon in each room while being allowed to drink all the coffee they like. (The order in which they sit in the rooms is rotated, so that half do their first afternoon in the Paris room and half in the San Francisco room.) The amount each student drinks is recorded below:
Cups of Coffee Consumed for each Motif

Participant   Paris   San Francisco
A   8.5      8.4
B   4.3      4.6
C   2.0      1.7
D   7.8      7.3
E   7.0      7.2
F   9.1      7.4
G   3.3      3.0
H   3.5      3.5
   Is there is’ a significant difference between the number of cups of coffee consumed in the two rooms (use the .05 level)?
