The Yankee Stadium food menu includes dirty fries and loaded
fries. Let D be the weight, in ounces, of a randomly selected order
of dirty fries. Let L be the weight, in ounces, of a randomly
selected order of loaded fries. Suppose D is normally distributed
with a mean weight of 5.2 ounces and a standard deviation of 0.4
ounces. Suppose L is normally distributed with a mean weight of 5.4
ounces and a standard deviation of 0.5 ounces. L and D are
independent.
a) Calculate the expected value of L + D. (in
ounces)
b) Calculate the standard deviation of L + D. (in
ounces)
c) What is the probability that an order of loaded fries weighs
less than 5 ounces?
d) What is the probability that an order of loaded fries weighs
between 5 and 6 ounces?
e) What is the 95th percentile of D?
f) What is the probability that L + D is greater than 11
ounces?
g) Suppose we purchase an order of loaded fries and an order of
dirty fries. What is the probability that each of the orders weighs
more than 5 ounces? (L>5 and D>5)
h) What is the probability that D is greater than
L?
