Answer:
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 Undecided Against 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:
[tex]E(X)=\frac{\text{Row Total}\times \text{Column Total}}{\text{TOTAL}}[/tex]
Compute the expected frequency for people against the project and who have over 120 feet of property foot frontage as follows:
[tex]E(X)=\frac{\text{Row Total}\times \text{Column Total}}{\text{TOTAL}}[/tex]
[tex]E(5)=\frac{10\times 39}{100}=\frac{39}{10}=3.9[/tex]
Thus, the expected frequency for people against the project and who have over 120 feet of property foot frontage is 3.9.
