A sports physiologist is investigating whether water or Gatorade provides the best hydration for athletes after training. A sample of 50 athletes between the ages of 18 and 30 was selected. On two consecutive days, each athlete ran 5 miles at a steady rate on a treadmill in a 75-degree room. On one of these days, 32 ounces of water was consumed after running. On the other day, 32 ounces of Gatorade was consumed after running. For each athlete, which beverage was consumed first was randomized. Hydration one hour after beverage consumption was measured, and results for the two beverages were compared. Which of the following is the best description of this study? (A) An experiment using a completely randomized design (B) An experiment using a matched-pairs design (C) An observational study using a simple random sample (D) An observational study using a cluster sample (E) An observational study using a stratified sample

Question
A sports physiologist is investigating whether water or Gatorade provides the best hydration for
athletes after training. A sample of 50 athletes between the ages of 18 and 30 was selected. On two
consecutive days, each athlete ran 5 miles at a steady rate on a treadmill in a 75-degree room. On
one of these days, 32 ounces of water was consumed after running. On the other day, 32 ounces of
Gatorade was consumed after running. For each athlete, which beverage was consumed first was
randomized. Hydration one hour after beverage consumption was measured, and results for the two
beverages were compared. Which of the following is the best description of this study?
(A) An experiment using a completely randomized design
(B) An experiment using a matched-pairs design
(C) An observational study using a simple random sample
(D) An observational study using a cluster sample
