a) Establish a control chart for moniloring the averape weights of the bowiling balls in which the upper and lower control imits are each two standard deviations from the mean. What aru the values of the controt timits? Upper Control Limit (UCL,-) =9.98 th. (round your response to two decimal placess) Lower Controt Limt (LCL)=9.51 ib. (round your response to two dectmal places) D) if enee standard deviations are used in the chart, what are the values of the control imta? Upper Control tims (UCLj)= b. (round your rosponse to two decimal places)
