just need the idle percentage in problem e please, still have not gotten a correct answer

Problem 6-5 (Algo) As part of a major plant renovation project, the Industrial engineering department has been asked to balance a revised assembly operation to achieve an output of 260 units per hour day. Task times and precedence relationships are as follows: Duration Immediate Task (inutes) Predecessor 3.1 0.6 0. Do each of the following a. Determine the number of followers for each task Number of tasks to owing taska Number of tasks following task Number of tanksfolowng tak Number of tasks to owing takde Number of tasks following asko Number of tasks towing at Number of following 1 1 Taw Prov Next b. Determine the minimum cycle time, the maximum cycle time, and the calculated cycle time. (Round all answers up to one decimal point. For example, round 1.83 up to 1.9.) Minimum cycle time Maximum cycle time Calculated cycle time 15 minutes per unit 55 minutes per unit 17 minutes per unit c. Determine the minimum number of stations needed. (Use your rounded cycle time from Part b. Round up your answer to a whole number. Note that rounding up to one decimal point may reduce output to slightly less than 260 and this is fine.) Mumm humber of stato S Prov 1 of 1 Next d. Use the calculated cycle time. Assign tasks to workstations on the basis of most following tasks. Use shortest processing time as a tiebreaker. If tles still exist, assume indifference in cholce. Workstations Following Tasks abo To IV 19 e Compute the percent idle time and percent officiency for the assignment in part d. Note: the calculated cycle time and the actual bottleneck station time are different, use the actual bottleneck time in your cakulations (Round your answers to 2 decimal places) Ide porcentage Elicency 0167
