Question

HW#9 - Chapter 18 (20pts for turned in on time) Pairedt test is when two dependent groups are compared with each other, and to perform a pairedt test, a Difference will be calculated first between each pair of the individuals of the two groups, and then a one-sample t test will be conducted on the Difference. 5. (10pts)There is evidence that cytotoxic T lymphocytes (T cells) participate in controlling tumor growth and that they can be harnessed to use the body's immune system to treat cancer. One study investigated the use of T cell-engaging antibody, blinatumomab, to recruit T cells to control tumor growth. The data below are T cell counts (1000 per microliter) at baseline (beginning of the study) and after 20 days on blinatumomab for 6 subjects in the study. The difference (after 20 days minus baseline) is the response variable. You are asked if the number of T cells after 20 days is higher. Baseline 0.04 0.02 0.00 0.02 0.38 0.33 After 20 0.28 0.47 1 .30 0.25 1.22 0.44 days Difference 0.24 0.45 1.30 0.23 0.84 0.11
