Questions PT 1.
I. The mean daily production of a herd of cows
is assumed to be normally distributed with a mean of 32 liters, and
standard deviation of 10.6 liters.
What is the probability that daily production is
between 47.4 and 59.6 liters? Do not round until
you get your your final answer.
II. A distribution of values is normal with a
mean of 9.4 and a standard deviation of 48.1.
Find the probability that a randomly selected value is greater than
-72.4.
P(X > -72.4) =
III. A company produces steel rods. The lengths
of the steel rods are normally distributed with a mean of 145.8-cm
and a standard deviation of 1.8-cm.
Find the probability that the length of a randomly selected steel
rod is less than 145.8-cm.
P(X < 145.8-cm) =
IV. In the country of United States of
Heightlandia, the height measurements of ten-year-old children are
approximately normally distributed with a mean of 55.1 inches, and
standard deviation of 2.3 inches.
A) What is the probability that a randomly chosen child has a
height of less than 59.55 inches?
B) What is the probability that a randomly chosen child has a
height of more than 51.6 inches?
V. A particular fruit's weights are normally distributed, with a mean of 476 grams and a standard deviation of 31 grams. The heaviest 13% of fruits weigh more than how many grams? Answer to the nearest gram.

Mean daily milk production for Jersey cows is 43 pounds with a known population standard deviation...
Mean daily milk production for Jersey cows is 43 pounds with a
known population standard deviation of 5 pounds and we know that
milk production for these cows follows a Normal model. Suppose a
farmer has a small herd of 20 Jersey cows. How do we know that the
distribution of the sample mean, , for the small herd of cows, is
approximately Normal?

1. Milk production requires the use of millions of
cows. Cows release methane gas and waste piles that can cause major
pollution problems. a. Is there too little, too much or
the correct amount of milk produced from a socially optimal
perspective? Prove your answer by drawing a graph representing the
market for milk that correctly identifies private and social
marginal benefit and marginal cost curves along with the market
equilibrium price and quantity versus the socially optimal
equilibrium price and...
