Exercises 19.8 and 19.10 Choose a college student at random and ask his or her class rank in high school. Probabilities for the outcomes are as follows: Rank top 20% second 20% third 20% lowest 40% Probability 0.40 0.30 0.20 ??? _ v What must be the probability that a randomly chosen A. Assign the digits as follows: student was in the bottom 40% of his or her high 0-4 represent top 20%; 0-3 represent second 20%; 0-2 school class? represent third 20% and 0-1 represent lowest 40%. _ v To simulate the class standing of randomly chosen B. 2 students, how would you assign digits to represent the C. 90% four possible outcomes listed? D. Assign the digits as follows: 0-3 represent top 20%; 4-6 represent second 20%; 7-8 represent third 20% and 9 represents lowest 40%. _ v The Random Foundation decides to offer 8 randomly E' 0'10 chosen students full college scholarships. What is the F. 9 probability that no more than 2 of the 8 students G 20% chosen are in the bottom 40% of their high school ' class? _ v Simulate 10 repetitions of the foundation's choices using line 119 of Table A. How many of your 10 samples have no more than 2 in the lowest 40%? QUESTION 3 Exercise 19.14 Using the tree diagram to explain how to simulate one repetition of Elaine's tries to pass the exam one correct model would be the following: The three tries are simulated by three consecutive random digits (stopping after a pass); 0 and 1 are a pass on the first try, 0, 1, and 2 a pass on the second try, and 0, 1, 2, and 3 a pass on the third try. 0 True O False 0.5 points Save
