A manager wants to determine an appropriate leaming percentage for processing insurance claims for storm damage. Toward that end, times have been recorded for completion of each of the first six repetitions. Use the following table for calculation. Learning curve coefficients a. Determine the approximate learning percentage. Hint. Compute this by averaging the various learning rate estimates available using the 'doubling' concept for all possible unit time ratios (e.g1,T2/T1,T4/T2. etc.) (Do not round intermediate calculations. Round your answer to the nearest 5 percent.) b. Using your rounded answer from part a, estimate the average completion time per repetition, assuming a total of 30 repetitions are planned. (Round your answer to 3 decimal places.)
