Question

Q- After reading the short description of the following situation, answer each of the questions below to the best of your ability.

Dr. Fitz has long been interested in the effects of alcohol on human behavior. His latest experiment involved giving college students one of three kinds of drinks: 3 ounces of vodka mixed with a standard size glass of orange juice, 2 ounces of vodka mixed with a small glass of orange juice, or 3 ounces of a nonalcoholic but vodka flavored drink mixed with a standard size glass of orange juice. Dr. Fitz recruited most of his subjects from this college's track team because he is an assistant coach. He recruited the rest of his subjects from his introductory psychology class. Dr. Fitz assigned the women on the track team to the "2 ounce vodka group", the men on the track team to the "3 ounce vodka group," and the women from his class to the "non-alcohol group." The women and men on the track team participated in the study right after they had finished practicing and the women from his class participated at various times during the day. After each subject had a chance to drink the beverage, he or she was asked to sit in an automobile simulator where the task involved stepping on the brake pedal as soon as possible after seeing a red light flash on a screen at the front of the simulator. Much to his surprise, subjects in the "2 ounce vodka group" showed slower reaction times to the red light than subjects in the "3 ounce vodka group." The nonalcoholic group showed the fastest reaction times. As soon as the study was over, Dr. Fitz told the subjects about the true purpose of the study and had each subject sign an informed consent form. From his analysis of the results, Dr. Fitz concluded that drinking alcohol can slow reaction time for braking in college students who drive after drinking.

1. Based on his experiment, is Dr. Fitz conclusion correct? From the options mentioned below, kindly bold your respective choice.

1. No, because he did not randomly select his subjects.
2. No, because he knew some of his subjects better than others.
3. Yes, because subjects in both experimental groups has slower reaction times than subjects in the control group.
4. Yes, because his results agree with what we all know from our experience with those who drink and drive.
5. No, because there were too many confounds in this experiment to draw a valid conclusion of his data, including a and b.

2. Give Dr. Fitz some advice on how he might improve his future search on the effects of alcohol.

Answer 1

Option C is the answer which is absolutely accurate.

Option C

Because here in this case it has been observed that Fitz consigned the ladies on the track group to the "2 ounce hard alcohol assembling", the fellows on the track bunch to the "3 ounce hard alcohol gathering," and along these lines the ladies from his bunch to the "non-alcohol gathering and men on the track group took half inside the assessment straightforwardly once that they had got past with practicing and thusly the women from his group shared at very surprising events for the duration of the day.

His most cutting-edge assessment encased giving students one among 3 assortments of refreshments: three ounces of hard alcohol mixing in with a standard size glass of pressed orange, two ounces of hard alcohol mixing in with a piece glass of crushed orange, or three ounces of a delicate by the by hard alcohol expanded savor mixing with a standard size glass of pressed orange.

Causing him a profound feeling of stun, subjects inside the 2 ounce hard alcohol gathering" demonstrated extra moderate reaction times to the red lightweight than subjects inside the 3 ounce hard alcohol assembling.The delicate social affair incontestable the quickest reaction times it makes it subjects in both experimental groups.
