Answer:
15 2/3
Step-by-step explanation:
11 feet + 4 2/3 feet = 15 2/3
11+4= 15 + 2/3 = 15 2/3
Its actually very simple.
The mean proportion is p = 36/120 = 0.3.
The standard deviation of the proportion will be sqrt(p*(1-p)/n) = sqrt(0.3*0.7/120) = 0.0418. We multiply this by the z-score of 1.645 to get a deviation of 0.0688.
Therefore, the confidence interval is (0.3 - 0.0688, 0.3 + 0.0688), which is
(0.2312, 0.3688).
