The answer is D. 64. Have a nice day!
Answer:
i know that the first one is not equivlent but i dont know about the others
Step-by-step explanation:
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).
|y-9|=6
y-9=6
y-9=-6
y=15
y=3
So, y=15,3
