A study was conducted to determine if the performance of a certain type of surgery on young horses had any effect on certain kinds of blood cell types in the animal. Fluid samples were taken from each of six foals before and after surgery. The samples were analyzed for the number of postoperative white blood cell (WBC) leukocytes. A preoperative measure of WBC leukocytes was also measured, with the accompanying results. Use a paired sample t-test to determine if there is a significant change in WBC leukocytes with the surgery. Click here to view the leukocyte data. Click here to view page 1 of the table of critical values of the t-distribution. Click here to view page 2 of the table of critical values of the t-distribution. Let sample 1 be the presurgery data, let sample 2 be the postsurgery data, and let μμ₁₂.
