Weight of three-month old puppies of the wild dog dingo is uniformly distributed between 4.5 lb and 7.5 lb. A random sample of 144 such puppies is selected.

Which probability is greater, the probability that a single randomly selected puppy has weight between 7 lb and 7.5 lb or the probability that the average weight of a randomly selected sample of 144 puppies is between 6.2 lb and 7.5 lb?

a. They are equal

b. The probability that a single randomly selected puppy has weight between 7 lb and 7.5 lb is greater.

c. The probability the average weight of a randomly selected sample of 144 puppies is between 6.2 lb and 7.5 lb is greater.

d. There is not enough information.
