Tourism is extremely important to the economy of Florida. Hotel occupancy is an often-reported measure of visitor volume and visitor activity (Orlando Sentinel, May 19, 2018). Hotel occupancy data
for February in two consecutive years are as follows.
Let P₁ = population proportion of rooms occupied for current year
P2 = population proportion of rooms occupied for previous year
Occupied Rooms
Total Rooms
1,360
1,700
