1.A study was conducted that compared the time to awaken from a general anesthetic for

ten orthopedic patients that had two knee replacements done in two separate surgeries,

with the anesthetic differing for surgeries on the first knee and the second knee. The

anesthetic used for the first knee replacement was the same for all 10 patients, as was the case for the second knee replacement in the patients. All surgeries were performed by the same surgeon. The study was interested in determining whether there was a difference in the time to awaken following surgery for the two different anesthetics. The data for the

ten patients are provided in the table below. Use these data to answer the question below

the table.

Patient Anesthetic 1 (1st Knee) Anesthetic 2 (2nd Knee) Time to awaken (in min) Time to awaken (in min) 142 138 2 140 136 3 144 147 4 144 139 5 142 143 6 146 141 7 149 143 8 150 145 9 142 136 10 148 146
