Refer to Assignment #1, Question 8: Y = Ei X₁ where X₁~ Exponential (3). (a) Show that = 2 is a pivotal quantity. 2Y b) Using your findings in (a), find a 95% confidence interval for 3. (c) The following data represent a random sample of n = 10 passengers who have entered a self-check in ticket kiosk at the Calgary International Airport. The time each passenger spent in line until they used the ticket kiosk was observed, in fractions of a minute. Presume the data below comes from a population of values that can be modeled by an Exponential distribution #x 3. Find a 95% confidence interval estimate for 3. In addition, interpret the meaning of your findings. 8.0 4.7 5.1 8.0 11.7 23.5 11.1 0.8 5.9 8.1 -
