In times of stress, some people hyperventilate to the point of dizziness and fainting. To determine whether this behavior is equally likely in men and women, a researcher takes a random sample of 25 cases from a hospital emergency room's file on those treated for hyperventilation.
a. What hypothesis should be tested about the percentage of males among those treated?
b. What should the region of rejection be if a is to be as near 0.01 as possible?
c. If 16 of the 25 persons in the sample are men, should the researcher conclude that men are more likely to hyperventilate than women? Why or why not?
