the questions are below for the chart posted please help!

A. Choudhury's bowling ball factory in Illinois makes bowling balls of adult size and weight only. The standard deviation in the weight of a bowling ball produced at the factory is known to be 0.24 pounds. Each day for 24 days, the average weight, in pounds, of 9 of the bowling balls produced that day has been assessed as follows: a) Establish a control chart for monitoring the average weights of the bowling balls in which the upper and lower control limits are each two standard deviations from the mean. What are the values of the control limits? Upper Control Limit (UCLx^)= Ib. (round your response to two decimal places). x=n=0.11lb. (round your response to two decimal places). The 2-sigma x-chart control limits are: Lower Control Limit (LCL)=9.56Ib. (round your response to two decimal places). b) If three standard deviations are used in the chart, how do these values change? Why? Does the standard deviation of the sampling distribution x change? Yes No The 3-sigma x-chart control limits are: Upper Control Limit (UCLx)=10.11lb. (round your response to two decimal places). Lower Control Limit (LCL)=9.45lb. (round your response to two decimal places). Recall that the higher the confidence level, the wider the confidence interval. The new limits are set for 99.73% confidence level and are wider
