Alcohol and Altitude The effect of alcoholconsumption on the body appears to be much greaterat high altitudes than at sea level. To test this theory, a scientist randomly selects 12 subjects and randomlydivides them into two groups of six each. One group¡s put into a chamber that simulates conditions at an altitude of 12,000 feet, and each subject ingests adrink containing 100 cubic centimeters (cc) of alcohol. The second group receives the same drink in achamber that simulates conditions at sea level. After 2hours, the amount of alcohol in the blood (grams per100 cc) for each subject is measured. The data areshown in the table. Do the data provide sufficient evidence to support the theory that average amount ofalcohol in the blood after 2 hours is greater at highaltitudes?
