The local amusement park was interested in the average wait time at their most popular roller coaster at the peak park time (2 p.m.). They selected 13 patrons and had them get in line between 2 and 3 p.m. Each was given a stopwatch to record the time they spent in line. The times recorded were as follows (in minutes;mean = 114.15): 118, 124, 108, 116, 99, 120, 148, 118, 119, 121, 45, 130, 118. What is the range?

A study of wait-times at the theme park found that the average ride-line length was 40 minutes with a standard deviation of 12 minutes. Assuming that wait times at the theme park are characterized by a normal distribution: What percent of guests wait longer than 60 minutes for a ride? What percent of guests wait less than 30 minutes for a ride? If you attend the theme park, what is the probability you will have to wait between 45 and...

Waiting in line (25 points) A quality- control manager at an amusement park feels that the amount of time that people spend waiting in line for the American Eagle roller coaster is too long. To determine if a new loading/unloading procedure is effective in reducing wait time in line, he measured the amount of time (in minutes) people are waiting in line for 7 days. After implementing the new procedure, he again measures the amount of time in minutes people...

During peak times the entry gate at a large amusement park experiences an average arrival of 30 customers per minute, according to a Poisson distribution. The average customer requires 12 seconds to be processed through the entry gate (exponential distribution). The park’s goal is to keep the time in the system (waiting time plus time through the gate) to less than 90 seconds. What is the minimum number of gates that are necessary to meet this goal? (Note that the...

An amusement park studied methods for decreasing the waiting time (minutes) for rides by loading and unloading riders more efficiently. Two alternative loading/unloading methods have been proposed. To account for potential differences due to the type of ride and the possible interaction between the method of loading and unloading and the type of ride, a factorial experiment was designed. Use the following data to test for any significant effect due to the loading and unloading method, the type of ride,...
