Problem 2. (1 point) The amount of time passing between successive customer check-ins to a downtown Calgary hotel can be modeled by an exponential distribution with a mean of 15 minutes. Remaining time: 32:50 (minzsec) (a) What can you say about the distribution oi the time passing between the successive check-ins of customers at this downtown Calgary hotel? f\" A. The distribution is right-skewed with a mean of 15 minutes and a standard deviation of 225 minutesz. f\" B. The distribution is left-skewed with a mean of 15 minutes and a standard deviation of 15 minutes. i\" C. The distribution is left-skewed with a mean of 15 minutes and a standard deviation of 225 minutesz. h D. The distribution is symmetrical with a mean of 15 minutes and a standard deviation of 15 minutes. A E. The distribution is right-skewed with a mean of 15 minutes and a standard deviation of 15 minutes. A F. The distribution is left-skewed with a mean of 15 minutes and a standard deviation of 3.87 minutes. A G. The distribution is right-skewed with a mean of 15 minutes and a standard deviation of 3.87 minutes. (b) Compute the probability that the amount of time passing between the arrival of successive customers who check-in is: (i) less than 8 minutes. E ' (Round to at least four decimals in your answer) (ii) between 9 and 18 minutes. ' E (Round to at least four decimals in your answer) (iii) more than 25 minutes. E (Round to at least four decimals in your answer) (0) If 12 minutes have passed since the last customer checked-in, what is the probability that at least another 7 minutes will pass until the next customer checks-in to this hotel? 5 (Round to at least four decimals in your answer) (d) 92% of the time, the number of minutes passing between successive customer checkins is at most how many minutes? E minutes (Round to at least two decimals in your answer) preview answers
