Over 120 feet 3 2 5 10
Total 50 11 39 100
The formula to compute the expected frequency is:

Compute the expected frequency for people against the project and who have over 120 feet of property foot frontage as follows:


Thus, the expected frequency for people against the project and who have over 120 feet of property foot frontage is 3.9.
