(R programming). A Researcher wants to test a new treatment for a particular skin condition. Ask to patients who come to participate in a trial where they will be randomly assigned to treatment standard or new treatment. He observes that the probability that such a patient agrees to participate in this essay is 0.3. (Assume the trials are independent)(Provide the script below) a) If you ask 25 patients to take part in the trial, find the probability that: i) 4 or less will agree ii) Exactly 6 will agree iii) more than 2 will agree. During a year, this doctor found a total of 40 patients who joined this investigation. He assumes that the probability of receiving the full treatment (from start to finish) is 0.14. b) Of the 15 patients receiving standard treatment, find the probability that no more of one withdraws before the end of the trial.
