Question 22: Xbar and R-charts have beenplotted for the pressure in aerosol cans. Thecenter line (CL) equals 60 psi (pounds persquare inch) and the upper control limit(UCL) equals 61. The sample size used inthe statistical process control of the filling ofthese cans equals 9 cans. What is thestandard deviation of the pressure inindividual cans?

Given, CL = R-bar = 60 UCL = 61 Sample size n = 9
