Practice: Group work • The waiting time at an elevator is uniformly distributed between 30 and 200 seconds. Find the mean and standard deviation of the waiting time. • A) 115 seconds and 49.07 seconds • B) 1.15 minutes and 0.4907 minutes • C) 1.15 minutes and 24.08333 (minute)2 • D) 115 seconds and 2408.3333 (second)2

Step 1
Given that the waiting time is uniformly distributed between 30 and 200 seconds, the mean can be calculated as: Mean = (30 + 200) / 2 Mean = 115 seconds Show more…

(a) Construct the distribution for the random variable X? (b) Find the mean and standard deviation of X. (c) What is the probability that the time between consecutive arrivals (customers) will fall between 3 and 6 minutes? QUESTION 4 The arrival time of an elevator in a 12-story building is equally likely at any range during next 4 minutes. (a) Calculate the expected arrival time. (b) Calculate the standard deviation of arrival time. (c) What is the probability that an elevator arrives in less than 90 seconds? (d) What is the probability that the wait time for an elevator is more than 120 seconds?

Use the following information to answer the next three exercises: The length of time it takes to find a parking space at 9 A.M. follows a normal distribution with a mean of five minutes and a standard deviation of two minutes. Seventy percent of the time, it takes more than how many minutes to find a parking space? a. 1.24 b. 2.41 c. 3.95 d. 6.05
