In a group of college students, the ratio of men to women is 3:1 (i.e., 3 to 1). In a recent survey, 65% of the men in this group selected hiking as their favorite outdoor activity whereas 50% of the women in the group selected hiking as their favorite outdoor activity. An individual is randomly selected from this group. What is the probability that hiking is not his/her favorite outdoor activity? Round your result to 2 significant places after the decimal (For example, 0.86732 should be entered as 0.87).
Homework Answers
P(Hiking is not his/ her favorite outdoor activity)
= P(Men)*P(Not hiking | Men) + P(Women)*P(Not Hiking | Women)
= (3/4)*(1 - 0.65) + (1/4)*(1 - 0.50)
= 0.3875
= 0.39

Scores for a common standardized college aptitude test are normally distributed with a mean of 485 and a standard deviation of 114. Randomly selected men are given a Test Prepartion Course before taking this test. Assume, for sake of argument, that the test has no effect. If 1 of the men is randomly selected, find the probability that his score is at least 536. P(X> 536) = Round to 4 decimal places. If 20 of the men are...
