(a) The drug is administered to one patient selected at random. Wwhat is the probability that the time it takes to go into effect is 35 minutes or less? (Round your answer to four decimal places.) 9452 (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? (Round your answer to four decimal places.) 3612 (c) Comment on the differences of the results in parts (a) and (b). The probability in part (b) is the same as vx the probability in part (a) because the standard deviation v is smaller vv for the x distribution.

Transcribed Image Text:A new muscle relaxant is available. 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.
