In a recent study of the long-term effects of concussions in football players, researchers at Virginia Tech concluded that 50% of college football players receive strong blows to the head that average 40 times the force of gravity. Suppose you select a SRS of 60 college football players and install sensors
on their helmets and record the number of strong blows to the head.
A) What is the mean of the sample distribution? (2 decimal places)
B) What is the standard deviation? (3 decimal places)
C) Is it Normal? (Yes or No)
D) What is the probability that in a sample of 60 football players that 45% or less of college football players receive strong blows to the head that
average 40 times the force of gravity? (3 decimal placers)
