photo below is the factor fir determining control limits dor x bar and r chart

Carefully examine the following table which contains weights (in oz) of boxes of raisins. Make sure you identify carefully the correct sample size before you start computations. Required: (a) Compute the upper and lower control limits for the R-chart. Then state whether the process is in control. You need not plot the data. Hint: Make sure you select/identify the correct sample size. Also, compute R-bar first! (b) Compute the UCL/LCL values for x-bar chart. Then, just by observation, state if the, process appears to be in control and state why you believe so. 231.881.02003.272.57 450.730.58002.282.11 60.480 90.340.181.82 100.310.221.78
