Researchers from the firm  developing the relaxant have done studies that indicate that the time lapse  between administration of the drug and beginning effects of the drug is normally  distributed, with mean u = 38 minutes and standard deviation o = 5 minutes. (a) The drug is administered to one patient selected at random. What is the  probability that the time it takes to go into effect is 35 minutes or less?   b) The drug is administered to a random sample of 10 patients. What is the  probability that the average time before it is effective for all 10 patients is  35 minutes or less?
