Subject Probabilities & Statistics Code: Semester: (Question 3) On average, 5 traffic accidents per month occur at a certain intersection. What is the probability that in any given month, at this intersection (a) fewer than 6 accidents will occur? (b) at least 3 accidents will occur? (Question 4) A fair coin is tossed seven times. What is the probability of obtaining five tails? Name: ID: Signature Question 8) Binomial Probability Distribution According the center for statistical research at the United Nations, 20% on U.S. teens enjoy taking mathematics classes. Suppose 10 U.S. teens are selected and the number who enjoys taking statistics is recorded. . [5 Points] What is the probability that exactly 2 will enjoy taking statistics? [7 Points] What is the probability that 2 or fewer will enjoy taking statistics? (3 Points) What is the probability that 3 or more will enjoy taking statistics? The following is the list of MAD statistics for each of the models you have estimated from time-series data: Model Linear Trend Quadratic Trend Exponential Trend AR(2) Based on the MAD criterion, the most appropriate model is Question 3 options: linear trend. quadradic trend. exponential trend.
