Can the introduction of pleasant sensory stimuli lead to a more pleasant exercise environment and decrease perceived exertion during a four‑minute stepping task? Forty‑three students from a Southeastern University were assigned at random to three conditions: "taste," in which participants inserted a lemon‑flavored mouth guard during the task; "placebo," in which participants inserted a non‑flavored mouth guard; and "control," in which no mouth guard was used. Twelve students were assigned to the taste group, 15 to the placebo group, and 16 to the control group. Ratings of perceived exertion (RPE) scores were measured on a standard 15‑point scale ranging from 6 (very, very light) to 20 (exhausted). Select the populations and the response variable. The population is all humans. The response is the rating of perceived exertion. The populations are students who wear a lemon‑flavored mouth guard and students who wear a non‑flavored mouth guard. The response is the rating of perceived exertion. The population is all college students. The response is the rating of perceived exertion. The populations are students who wear a lemon‑flavored mouth guard, students who wear a non‑flavored mouth guard, and students who wear no mouth guard.

Question

Can the introduction of pleasant sensory stimuli lead to a more pleasant exercise environment and decrease perceived exertion during a four‑minute stepping task? Forty‑three students from a Southeastern University were assigned at random to three conditions: "taste," in which participants inserted a lemon‑flavored mouth guard during the task; "placebo," in which participants inserted a non‑flavored mouth guard; and "control," in which no mouth guard was used. Twelve students were assigned to the taste group, 15 to the placebo group, and 16 to the control group. Ratings of perceived exertion (RPE) scores were measured on a standard 15‑point scale ranging from 6 (very, very light) to 20 (exhausted).

Select the populations and the response variable.

The population is all humans. The response is the rating of perceived exertion.

The populations are students who wear a lemon‑flavored mouth guard and students who wear a non‑flavored mouth guard. The response is the rating of perceived exertion.

The population is all college students. The response is the rating of perceived exertion.

The populations are students who wear a lemon‑flavored mouth guard, students who wear a non‑flavored mouth guard, and students who wear no mouth guard. The response is the rating of perceived exertion.
