Answer:
c. 0.0819
Explanation:
The mean = 0.85
standard error of the proportion is: sp = sqrt(pq/n)
= sqrt ((.85)(0.15) / 51) = 0.05
P(0.9115 < X < 0.946) = P( (0.9115 - 0.85) / 0.05 < z < (0.946 - 0.85) / 0.05 )
= P(1.23 < z < 1.92)
= P(z < 1.92) - P(z < 1.23) = 0.0819
Answer:
The answer to the question would be C
