The waiting times for a new roller coaster ride are normally distributed with a mean of 35 minutes and a standard deviation of 10 minutes. If there are 150,000 riders the first summer, which of the following is the shortest time interval associated with 100,000 riders? A. 0 to 31.7 minutes B. 31.7 to 39.3 minutes C. 25.3 to 44.7 minutes D. 25.3 to 35 minutes E. 39.3 to 95 minutes

On a busy day, the average roller coaster wait time at a large amusement park is 27 minutes. Suppose the standard deviation of wait time is 11.9 minutes and the distribution of wait times is approximately normally distributed. a) If it's a busy day, approximately what percentage of people at the amusement park will have a wait time that is at least 30 minutes? Round to the nearest whole percent. b) To improve customer satisfaction, the amusement park manager has decided to give food coupons to customers with long wait times. The manager decided to give the coupons to the top 10% of people waiting the longest. What is the minimum wait time for the top 10%? Round to the nearest tenth of a minute.

During the summer months, there is often a long wait to ride a popular roller coaster at the Super Fun Amusement Park. One summer day, Jamie waited 29 minutes to ride the roller coaster, which is the quartile 1 value for wait times. A few days later, Jessie waited 38 minutes, which is at the 70th percentile for wait times. Assuming the distribution of wait times is roughly normal, what is the approximate mean wait time to ride this roller coaster during the summer months? Select one answer: A) 27.14 minutes B) 33.50 minutes C) 34.06 minutes D) 36.27 minutes E) 58.00 minutes
