Question
For each probability and percentile problem, draw the picture. According to a study by Dr. John McDougall of his live-in weight loss program at St. Helena Hospital, the people who follow his program lose between 6 and 15 pounds a month until they approach trim body weight. Let's suppose that the weight loss is uniformly distributed. We are interested in the weight loss of a randomly selected individual following the program for one month. †
a) State "P(6 < X < 13 | X > 11) = ___" in a probability question.
b) Draw the picture and find the probability. (Enter your answer as a fraction.
Explanation / Answer
a)State "P(6 < X < 13 | X > 11) represent that weight loss is between 6 and 13 pounds given weight loss is greater then 11.
b)P(6 < X < 13 | X > 11)= P(6<X<13 and X>11)/P(X>11) =P(11<X<13)/P(X>11) =((13-11)/(15-6))/((15-11)/(15-6))
=2/4 =1/2
