A medical research team studied the number of head and neck
injuries sustained by hockey players. Of the 310 players who wore a
full-face shield, 175 sustained an injury. Of the 402 players who
wore a half-face shield, 252 sustained an injury. At α = 0.10, can
you reject the claim that the proportions of players sustaining
head and neck injuries are the same for the two groups?
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.

In how many ways can you arrange the members of two committees
of 11 males and 11 females around a circular table if the only
thing that matters is who the neighbors of each committee member
are on each side (having person 1 on the right and person 2 on the
left is different from having person 1 on the left and person 2 on
the right), and not who sits in which chair if:
1. There are no restrictions...
