Please can you assist by showing me how to perform questions 5,c in Minitab? I cannot get the distribution to allocate correctly. 25% of the control group of 240 is to receive the placebo.

Question 5 [Unit 11} . marks You will need to use Minitah to answer this question. A clinical trial is being designed to compare drug A against a placebo in the treatment of a disease. The researchers want to collect more information from the patients on drug A and so have decided to use a 3 : 1 random allocation to drug A rather than a 1 : 1 random allocation. A 3 : 1 random allocation means that, for each patient, there is a 75% chance of being allocated drug A and a 25% chance of being allocated the placebo. The trial is planning to recruit 240 patients. In order to assign the EM] patients to a treatment group, you will need to allocate patients at random so that approximately ?5% of them receive drug A {group 1} and the rest are allocated to the placebo group {group D}. Eon Minitab. {a} Howr many patients would you expect to allocate to the placebo group? {b} Set the seed of Minitab's random number generator to the value 33. Why do you think that you have been asked to do this?II {c} Use the appropriate facilities of Minitab to assign each of the 2m patients to placebo [group [1] or drug A {group 1} at random, with probability [1.75 that a patient will be in the drug A group. [i] State what method you used to allocate patients to groups. E.g. 'I used the method described in Computer Activity K'. {ii} How many patients are randomised to receive the placebo (group n}? [iii] Using worksheet row numbers as patient ID numbers, list the rst ten IDs of the patients who will be assigned to the placebo group. {d} Comment on the outcome of the allocation of patients to the placebo group that you obtained in part {c} compared with the number you expected in part [a].
