please step by step and

with control chart (graph)

The data in Table 1 are 7 and R vaives for 25 samples of size a = 4 taken from a process filling bags of fertilizer. The measurements are made on the 111 weight of the bags in kilograms Table 1 x R P R R Sample Number 2 303 29.6 308 309 29.8 30.5 302 299 30.0 30.1 302 305 304 0.73 0.75 0.79 0.74 0.72 0.73 0.71 0.70 0.65 0.67 0.65 0.67 0.68 Sample Number 14 15 16 17 18 19 20 30.8 30.0 29.9 30.4 30.5 30.7 30.2 0.70 0.65 0.66 0.67 0.68 0.70 0.65 0.60 0.64 0.60 8 9 10 11 12 13 30.1 29.5 30.0 30.3 0.62 0.60 Set up and interpent and R chart on this process. Does the process seem to be in control? If necessary, anume assignable causes and revise the trial control limits (ii) If the average fill of the bags is to be 30.0 kilograms, how does this process compare
