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

Step-by-step explanation:

The data provided is:

                                                   Opinion    

Front Footage   For       UndecidedAgainst    Total

Under 45 feet    12                4              4              20

  45-120 feet           35                5             30      70

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.
