Question

The mean daily production of a herd of cows is assumed to be normally distributed with a mean of 36 liters, and standard deviation of 4.8 liters. A) What is the probability that daily production is less than 45.7 liters? Answer= (Round your answer to 4 decimal places.) B) What is the probability that daily production is more than 22.8 liters? Answer= (Round your answer to 4 decimal places.) Warning: Do not use the Z Normal Tables...they may not be accurate enough since WAMAP may look for more accuracy than comes from the table.

Answer #1

a) P(x < 45.7)=?

The z-score at x = 45.7 is,

z = 2.0208

This implies that

P(x < 45.7) = P(z < 2.0208) = **0.9784**

b) P(x > 22.8)=?

The z-score at x = 22.8 is,

z = -2.75

This implies that

P(x > 22.8) = P(z > -2.75) = 1 - 0.003

P(x > 22.8) = **0.997**
