A cardiologist is studying the distribution of pulse rates in junior tennis players. He is concerned that this group of teenagers may have enlarged hearts which can be reflected in inflated pulse rates. Using a large random sample of such athletes, he wants to establish a set of values of the resting pulse rates for these athletes such that the set of values would have a very high degree of certainty of containing 90% of the resting pulse rates for all such athletes.

A. The computed interval would be aconfidence interval.

B. The computed interval would be atolerance interval.

C. The computed interval would be aprediction interval.

D. The computed interval would be anatural interval.

E. None of the above would be appropriate.
