A time study was conducted on a task that consists of four elements. The observations and performance ratings for six cycles are shown in the following table. Observations (minutes per cycle) Element Performance Rating 1 2 3 5 6 98% 0.47 0. 43 0. 49 0.44 0.48 0.50 82 1.54 1.52 1.49 1.52 1.51 1.42 125 0.85 0.76 0.79 0.82 0.84 0. 89 110 1. 17 1.22 1.22 1.18 1. 28 1.11 a. Calculate the average time for each element. (Round the final answers to 2 decimal places.) Element Performance Rating OT 98% minutes 82 minutes W 125 minutes 110 minutes b. Calculate the normal time for each element. (Round the final answers to 3 decimal places.) Element Performance Rating NT 98% minutes 82 minutes SUNK 125 minutes 110 minutes
