You’ve just completed a pilot run of 10 units of a major product and found the processing time for each unit was as follows: UNIT: NUMBER TIME (HOURS) 1:810 2:620 3:570 4:500 5:480 6:460 7:440 8:420 9 :395 10:380 a. According to the pilot run, what would you estimate the learning rate to be? (Do not round intermediate calculations. Round your answer to the nearest whole percent.) b. Based on (a), how much time would it take for the next 190 units, assuming no loss of learning? (Round your answer to the nearest whole number.) c. How much time would it take to make the 1,000th unit? (Round your answer to the nearest whole number.)
