## Problem

Rashad is a hotel manager. He surveyed a random sample of 120 guests and asked them which floor their room was and about their level of satisfaction. Here are the results:
Hotel floorSatisfiedNeutralNot satisfiedTotal
1-32011839
4-62413643
7-9start box, 23, end box10538
Total673419120
Rashad wants to perform a \chi, squared test of independence between floor and satisfaction.
What is the expected count for the cell corresponding to satisfied guests that stayed in floors 7 to 9?
