A study was conducted at the Department of Veterinary Medicine at Virginia Tech to determine if the “strength” of a wound from surgical incision is affected by the temperature of the knife. Eight dogs were used in the experiment. “Hot” and “cold” incisions were made on the abdomen of each dog, and the strength was measured. The resulting data appear below. Determine if there is a significant difference in strength between the hot and cold incisions. Use a significance level of 0.05. a. What type of Hypothesis Testing should be used? b. What are the null and alternative hypothesis? c. What is the critical value? d. What is the standardized test statistic? e. What is the Statistical Decision?
