Problem

During a meeting, one hospital administrator indicated that 70% of the geriatric patients are males.

a. What is the sample proportion of male patients?

b. Assumiong that the administrator is correct, what is the probability that a sample of this size would have a sample proportion as extremem or more extreme than the one you found in part a?

c. Would you conclude that the adminstrrator's assertion concerning the proportion of male geriatric patients is correct? Justiy your answer?
