Answer:
the sample size n= 771
sample proportion is p = 1/2
Step-by-step explanation:
<u>Step1:</u>-
marginal error formula is 
but if 'n' is sample size then 
Given margin error is 36% = 0.036

on simplification , we get n= 777 polling agencies
<u>Step 2</u>:-

substitute values , we get

after simplification, we get

squaring on both sides, we get

multiply 'p' inside

cross multiplication '4' and simplify
........(1)
finding 'p' value
The equation (1) is of the form 



<u>conclusion</u>:-
The sample size is 771
the sample proportion is p =
