Additional Problem 10-3 (Algo) A driverless car manufacturer tests the quality of the batteries of cars by measuring how long it takes to fully charge a car. For a given model, they investigate 5 different cars on 10 days. The standard deviation for charging time is 3.5 and the average charging times are given for each day in the table below: (https://en.wikipedia.org/wiki/Tesla Supercharger) Day 1 Day 2 Day 3 Day 4 Day 5 Day 6 Day 7 Day 8 Day 9 Day 10 Average charging time in minutes on each day 73 75 76 71 74 73 77 72 78 74 b. What are the upper and lower control limits (consider two-sigma limits)? (Round your answer to two decimal places.) Upper Control Limit Lower Control Limit c. What are the upper and lower control limits considering three-sigma limits instead of two-sigma? (Round your answer to two decimal places.) Upper Control Limit Lower Control Limit
