A manager wishes to build a 3-sigma range chart for a process. The sample size is five, the mean of sample means is 45.00, and the average range is 7.90. From Table S6.1, the appropriate value of D3 is 0, and D4 is 2.115. What are the UCL and LCL, respectively, for this range chart? (Do not round intermediate calculations. Round final answer to two decimal places.) OA. 12.05 and 0.00 OB. 10.02 and 5.79 O C. 16.71 and 0.00 O D. 68.70 and 21.30 OE. 52.90 and 37.10

This exercise contains only parts a and b. ​a) For the given​ data, the x= ____ hours ​(round your response to three decimal​ places). For the given​ data, mean range​ =_____hours ​(round your response to two decimal​ places). With ​z=3​, the control limits for the mean chart​ are:                                                  UCLx= ____hours ​(round your response to three decimal​ places).                                                LCLx​=____hours ​(round your response to three decimal​ places). The control limits for the range chart​ are:                                                UCLR​=____hours ​(round your response to two decimal​ places).                                                LCLR=h____ours ​(round your response to two decimal​ places). With these limits​ established, West now takes 5 more hours of​ data, which are shown in the following table. Calculate the mean and range for each hour that the sample data is taken. ​(Enter your responses for the mean to…
