The number of people entering a security check-in lineup in a 15-minute interval at a medium sized airport can be modeled by the following probability model: e-17(17)- P(X = x) = х 3D 0, 1, 2, .... Part (a) What does 17 represent in the probability model? Select the most appropriate explanation below. O A. 17 represents how much skewed the distribution of values is. O B. 17 is the rate at which people enter the security check-in lineup every 15 minutes. OC. 17 represents the average number of people who enter the a security check-in lineup every 15-minutes. OD. 17 is the standard deviation of the distribution of people entering the security check-in lineup every 15-minutes. O E. 17 represents a weighted-average of the number of people who enter the a security check-in lineup every 15-minutes. Part (b) Compute the probability that 18 people enter the security check-in lineup in a 15-minute interval. Use four decimals in your answer.
