The average weight of a football players on a team has been
computed to be 235.5 pounds with a standard deviation of 30.5
pounds. What is the probability that a random sample of 100 players
will weigh more than 24,000 pounds?

Expert Solution
Let weight of each player be denoted by X.
By Central Limit Theorem,
follows Normal Distribution with mean =
and variance =
It is suggested that the true average weight of college
football players is 200 lb. In a sample of 30 players, the sample
average is 206.73 lb. The sample standard deviation is 6.35 lb.
Does the true average weight differ from what was suggested? Test
the appropriate hypotheses about the true average weight of college
football players. Use α=0.05.
There are 80 players on the Rams Football Team. Assume that the
list of players' heights is a normally distributed data set. The
average of their heights is a normally distributed data set. The
average of their heights is 73 inches (6'1") and the standard
deviation is 3 inches.
a) Estimate the number of players who have height between 70 and
76 inches.
b) The Rams play the Chargers, whose players heights had an
average of 42 inches and a...
