1 multiple choice STATISTIC question?! 10 pts!!! ?

A medical researcher suspects that giving​ post-surgical patients large doses of vitamin E will speed their recovery times by helping their incisions heal more quickly. Design an experiment to test this conjecture.

a) Give the patients who agree to the study large doses of vitamin E after surgery. Monitor their​ progress, recording the time until they have reached an easily agreed upon level of healing. Compare the number of days under recovery of these patients to past records of​ post-surgery patients that did not receive large doses of vitamin E.

b)Randomly select half of the patients who agree to the study to get large doses of vitamin E after surgery. Give the other half a​ similar-looking placebo pill. Monitor their​ progress, recording the time until they have reached an easily agreed upon level of healing. Have the evaluating doctor blinded to whether the patient received the placebo or not. Compare the number of days under recovery of the two groups.

c)Give the first half of the patients who agree to the study to get large doses of vitamin E after surgery. Give the second half a​ similar-looking placebo pill. Monitor their​ progress, recording the time until they have reached an easily agreed upon level of healing. Compare the number of days under recovery of the two groups.
