In statistical process control, the hourly samples are taken. The sample means are: 156.46, 199.62, 189.31, 102.22 and 112.09 respectively Also, the ranges of these samples are 11.97.12.17.13.94, 11.86, and 11.83 respectively. If the upper controllimit of R chart is 26.07, what is the sample size of each sample? O a 5 b. 6 oc 4 d. None is correct De 7 Alocal toy manufacturer is using a production line that runs 8 hours per day and produces a toy that requires a total of 7 tasks to be performed The daily demand is 100 toys. Times of the tasks are 273,201,2.13,20,261, 271, and 2.95 minutes for A.B.C,D,E,F, and G, respectively. However, due to the nature of the product there are precedence rules that must be observed. Such that Task A does not need any predecessors task Brequires task A to be completed. To start task and task D, each require task B to be completed. Task C must be completed prior to stating task E. Task Freeds both task D and task Eto be completed. Finally, task G can start only once task Fis completed Giver we apply the most remaining tasks rule for balancing the assembly line, with ties broken according to longest task time first, the tasks that will be assigned to the FIRST workstation are_ O a Bonly b. A.B, and OC None is the correct answer Od A only e Aand B
