A veterinarian wishes to compare the number of times race horses are reported to be lame during a 12-month period, as compared with similar horses that are not raced. The veterinarian is particularly interested in whether the exercise chedule used in racing contributes to lameness, rather than the total amount of exercise. The veterinarian chooses nine ace horses and selects, for each race horse, a jumping horse that is the same age, the same breed, and exercised a simila umber of hours each week. The given table contains the observed number of times a horse was lame. Group 1 2 3 4 5 6 789 Race 7 8 2 3 1 4 2 6.

A veterinarian wishes to compare the number of times race horses are reported to be lame during a 12-month period, as
compared with similar horses that are not raced. The veterinarian is particularly interested in whether the exercise
schedule used in racing contributes to lameness, rather than the total amount of exercise. The veterinarian chooses nine
race horses and selects, for each race horse, a jumping horse that is the same age, the same breed, and exercised a similar
number of hours each week. The given table contains the observed number of times a horse was lame.

The veterinarian tests the hypotheses Ho :µ = 0 versus H : µ > 0, where u is the average difference in number of
times race horses are lame minus the number of times jumping horses are lame.
The P-value is:

between 0.2 and 0.3.
< 0.1.
between 0.1 and 0.2.
