23. During an experiment using laboratory animals the following data on renal cortical blood flow during control conditions and during the administration of a certain anesthetic were recorded.

Animal Number Renal Cortical Blood Flow

(ml / g / min)

Control During Administration of Anesthetic 1 2.35 2.00 2 2.55 1.71 3 1.95 2.22 4 2.79 2.71 5 3.21 1.83 6 2.97 2.14 7 3.44 3.72 8 2.58 2.10 9 2.66 2.58 10 2.31 1.32 11 3.43 3.70 12 2.37 1.59 13 1.82 2.07 14 2.98 2.15 15 2.53 2.05 Can one conclude on the basis of these data that the anesthetic retards renal cortical blood flow? Let a = .05. Determine the p value.
