A study of male navy enlisted personnel was reported in the Bloomington, Illinois on
Daily Pantagraph (Aug. 23, 1993). It was found that 90 of 231 left-handers had been hospitalized for
injuries, whereas 623 of 2148 right-handers had been hospitalized for injuries.
Let p denote the hospitalization rate for injuries among all male navy enlisted personnel. To investigate
whether there is a strong association between handedness and proneness to injury, let på and på denote
the proportion of being hospitalized for injuries among the left-handers and among right-handers,
respectively.
(a) Suppose that it has been previously reported elsewhere that the hospitalization rate for injuries
is about 20%, i.e., p = 0.20. For n = 231 + 2148 = 2, 379 randomly selected navy enlisted males,
let X denote the number of those who have ever been hospitalized for injuries.

What is the distribution of X? What is the expected value and variance of X?
