Answer: 0.355,0.405)
Step-by-step explanation:
Given : Significance level : 
Number of subjects (n) = 2455
Number of surveys returned = 931
The probability of surveys get return will be :-

The confidence interval for proportion is given by :-


Hence, the 99% confidence interval for the proportion of returned surveys : (0.355,0.405)
(a/bc) - d = x is the answer
4 feet 4 inches is the answer.. 12 inches in a foot
