The pucks used by the National Hockey League for ice hockey must weigh between 5.5 and 6.0 ounces. Suppose the weights of pucks produced at a factory are normally distributed with a mean of 5.75 ounces and a standard deviation of 0.11 ounces. What percentage of pucks produced at this factory cannot be used by the National Hockey League?
Solutions
Expert Solution
X : the weights of pucks produced at a factory
X ~ N (5.75, 0.11)
the probability that the pucks are between 5.5 ounces and 6.0 ounces is:-
[ in any blank cell of excel type =NORMSDIST(2.2727)]
the percentage of pucks produced at this factory cannot be used by the National Hockey League is:-
%

The drawing shows a collision between two pucks on an air-hockey
table. Puck A has a mass of 0.0290 kg and is moving along the x
axis with a velocity of +6.85 m/s. It makes a collision with puck
B, which has a mass of 0.0580 kg and is initially at rest. The
collision is not head-on. After the collision, the two pucks fly
apart with the angles shown in the drawing. Find the speed of (a)
puck A and...

One factor in rating a National Hockey League team is the mean
weight of its players. A random sample of players from the Detroit
Red Wings was obtained. The weight (in pounds) of each player was
carefully measured, and the resulting data have a sample size of 18
with a sample mean of 205 pounds and a sample standard deviation of
11.6 pounds. You can assume that all of the assumptions are
met.

The National Hockey League (NHL) has 80% of its players born outside the United States, and of those born outside the United States, 50% are born in Canada. Suppose that n=12 NHL players were selected at random. Let x be the number of players in the sample who were born outside of the United States so that p=.8. Find the following probabilities: a. At least five or more of the sample players were born outside the United States. b. Exactly...
