Extracted text: 5. A certain study involved patients whose melanoma did not respond to existing treatments. The presence of cells that trigger an immune response in the body is monitored since they may help fight cancer. Here are data for the 11 subjects: counts of active cells per 100,000 cells before and after infusion of the modified cells. Before 14 20 1 6 After 41 7 1 215 20 700 13 530 35 92 108 Construct a 95% confidence interval for the difference in the mean counts of active cells per 100,000 cells.
