how can I solve this by hand?

6.5. The data shown in Table 6E.2 are the deviations from nominal diameter for holes drilled din a carbon-fiber composite material used in aerospace manufacturing. The values reported are deviations from nominal in tenthousandths of an inch. (a) Set up x and R charts on the process. Is the process in statistical control? (b) Estimate the process standard deviation using the range method. (c) If specifications are at nominal \pm 100 , what can you say about the capability of this process? Calculate the PCR Cp
