(a) Write an appropriate hypothesis to determine if there is a significant difference in strength between the hot and cold incisions. (b) Test the hypothesis using a paired t-test. Use a P-value in your conclusion.

10.53 A study was conducted at Virginia Tech to de-
termine if the "strength" of a wound from surgical inci-
sion 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.
