5. The following table shows the number of completed passes for the two
quarterbacks each game for 16 games. Which quarterback has the higher mean?
Explain what this means in the context of the problem.
Quarterback 1 22 20 15 18 19 25 28 15 21 20 25 25 26 26 21 20
Quarterback 2 28 18 21 16 21 25 25 21 28 21 23 19 28 18 21 28
a. QB1 has a higher mean, but QB2 throws more passes.
b. QB2 has a higher mean, which tells us that on average he throws a higher percent
of completions.
c. QB2 has the higher mean which tells us that on average he throws more
completed passes than QB1
d. The standard deviation is the same for both quarterbacks, which tells us they are
equally accurate passers.
