I really need some help with this. Thanks!
Pulley Engineering manufactures needle bearings for use in high-tech machinery. The target diameter for one particular bearing is 200 mm. To inoriterte precision of the bearing diameter, the Head Engineer of Pulley Engineering plans to use appropriate control charts to keep track of the accuracy of the bearing diameters. To implement his plan, the Head Engineer instructed the quality control staff to collect daily samples, each of five observation for consecutive period of 20 days ("InitialData"). The quality control team would then use the initial Data (e. the 20-day data) to determine the location or the centerlines 'upper controllimits (UCL), and the lower controllimits (LCL) for the bar x control chart chart) and the R-chart. The Header and the quality control team would then use control charts to track the average diameters and their fluctuation ranges of the subsequently produced bearings. Table - 1 and Table - 2 below are the data for respectively, the 20 daily samples ("InitialData") and the subsequent production butches Table-1: Initial Data for Contructing Control Charts: Days S: S2 S3 54 Ss 1 206 196 206 202 199 2 191 195 206 202 197 3 198 205 203 197 198 4 194 208 197 210 205 5 209 201 198 192 199 6 196 206 199 201 199 7 207 196 202 190 204 204 190 190 206 201 204 191 193 206 195 10 190 205 193 204 210 11 203 203 198 200 12 205 194 209 201 190 13 1914 200 193 195 201 195 205 191 199 200 15 194 190 205 190 207 16 200 202 307 210 196 17 209 193 209 204 200 200 200 193 19 195 193 192 200 190 9 196 192 200 S4 SS 204 206 200 205 205 203 Table-2: Subsequent Production Data Subsequent Si S2 S3 Days 21 201 200 205 22 208 202 206 23 203 203 200 24 206 207 205 25 206 203 200 26 203 198 206 27 201 204 205 28 201 205 206 29 206 205 207 30 201 199 205 207 206 199 206 198 203 202 208 205 204 202 206 205 203 Required 1: 1.
