Bath concentrations are measured hourly in a chemical process. Data(in ppm) for the last 32 hours are shown in below data (please read down the columns to understand the order that the measurements were taken.) The process target is Mo=175 160 186 190 206 158 195 189 210 150 179 185 216 151 184 182 212 153 175 181 211 154 192 180 202 158 186 183 205 162 197 186 197 A. Estimate the process standart deviation B. Construct either a tabular or chart cusum for this process using standardized values of h=5 and k=0.5 C. Is the process in or out of control?
