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 buttps://en.wikipedia.org/wiw Testa Supercharger) Day Day 73 Day 2 75 Daya 76 Day 4 Day 5 73 74 Day 6 73 Day 72 Average charging time in minutes on each day Day Day To 78 74 77 a. What control chart con determine if the charging process is in control? Process control chart b. What are the upper and lower control limits (consider two-sigma ilmits)? (Round your answer to two decimal places.) Upper Control Limit Lower Control Limit c. What are the upper and lower controllimits considering three-sigma limits instead of two sigma? (Round your answer to two decimal places.) Upper Control Limit Lower Control Limit d. How do you interpret your results under two sigma limits and three sigma limits? Two sigma limits Three sigma limits
