If it does not, state why. 6 X 2 5 6 8 10 P(X) 2/ 11 1/ 11 3/ 11 3/ 11 1/ 11 This is a probability distribution 7 X 3 6 8 12 P(X) 0.3 0.5 0.7-0.8 This is not a probability distribution, since P(X) cannot = -0.8 8 X 3 6 8 P(X)-0.3 0.6 0.7 This is not a probability distribution, since P(X) cannot = -0.3 9 X 1 2 3 4 5 P(X) 3/ 10 1/ 10 1/ 10 1/ 5 3/ 10 This is a probability distribution 10 X 20 30 40 50 P(X) 0.05 0.35 0.4 0.2 This is a probability distribution 11 X 5 10 15 P(X) 1.2 0.3 0.5 This is not a probability distribution, since P(X) cannot = 1.2 For Excersies 12 through 18, state whether the variable is discrete or continuous. 12 The speed of a jet plane. Continuous 13 The number of cheese burgers a fast-food restaurant serves each day. Discrete 14 The number of people who play the state lottery each day. Discrete 15 The weight of a Siberian tiger. Continuous 16 The time it takes to complete a marathon. Continuous 17 The number of mathematics majors in your school. Discrete 18 The blood pressures of all patients admitted to a hospital on a specific day. Continuous For Exercises 19 through 26, construct a probability distribution for the data and draw a graph for the distribution. 19 X 1 2 3 P(X) 2/ 5 1/ 3 1/ 5 1/ 15 26 X 1 2 3 P(X) 0.22 0.33 0.37 0.08 30 Die 1 Die 2 1 2 3 4 5 6 1 1,1 1,2 1,3 1,4 1,5 1,6 2 2,1 2,2 2,3 2,4 2,5 2,6 3 3,1 3,2 3,3 3,4 3,5 3,6 1 2 3 0/ 1 1/ 20 1/ 10 3/ 20 1/ 5 1/ 4 3/ 10 7/ 20 2/ 5 9/ 20 Number of medical tests Probability 1 2 3 0.05 0.1 0.15 0.2 0.25 0.3 0.35 0.4 Number of cars Probability 4 4,1 4,2 4,3 4,4 4,5 4,6 5 5,1 5,2 5,3 5,4 5,5 5,6 6 6,1 6,2 6,3 6,4...
