QUESTION 6 The amount of time for an oil change at a particular service station is normally distributed with a mean of 23.2 minutes and a standard deviation of 3.8 minutes. Find each value below. Round all answers to two decimal places. Type the number only; do not include units. What length of time separates the top 3% of oil change durations at this station? minutes What length of time separates the bottom 15% of oil change durations at this station? minutes What are the two lengths of time that have, between them, the middle 90% of oil change durations at this station? (You will find two values, a lower endpoint and an upper endpoint. Between these values is the middle 90% of observations for this distribution.) Lower endpoint: minutes Upper endpoint: minutes
