i need number 5 and 6

Problem Statement: A local thobe manufacturing facility works for 16 hours a day in two different shifts (8-hours) per shift. The facility produces different product. A quality engineer has recently joined the company, and the engineer was assigned for item number 512. This item is produced in mass quantities. The facility produces on average 90 thobes per day of this item. The following table shows the multiple subgroups of production of this item using multiple observations. The data shows the length of the item from shoulder to ankle joint. For this item, ideally the length should be 140 cm, and the customer can accept a tolerance of 2 cm. 150 -- -++ Subgroups XI 1138 2 146 142 148 5 151 6138 7 146 8140 9 138 10 152 11 139 12 148 13 142 14 139 15 145 16 153 17 18 138 19 147 20 147 21 137 22 142 23 138 24 149 25 151 26 150 Observations X2 X3 X Xs 153 138 142 146 150 147 150 152 151 147 137 146 140 143 147 150 147 146 151 144 150 146 153 151 142 140 150 142 140 143 146 147 153144 146 137 153 148 149 153 139 140 150 148 152 145 143 147 137 140 151 138 137 145 153 144 149 151 149 143 140 150 147 137 146 140 143 153 152 145 139 153 149 146 147 146 147 153 146 141 146 141 142 137 150 143 45138 150 137 144 141 137 141 145 152 151 141 148 145 149 152 147 152 140 149 139 140 150 146 152 138 143 139 147 145 142 143 143 140 153 148 151 146 148 137 148 147 144 144 1. Analyze the data using X-R chart and X-Schart. 2. On the basis of range and standard deviation, determine the process capability and apply capability analysis by calculating Co and Cpik 3. Do you see a variability of the data? 4. How can you improve the process? 5. What conclusions you can draw from the results? 6. As an IE, what other recommendations do you have for the manufacturing facility
