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 effect of the drug is
normally distributed, with mean μ= 38 minutes and standard
deviation σ= 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 effectice for all 10 patients is 35
minutes or less?
(C) Explain the differences in
the results you found.
(D) What types of studies and
information do you think drug companies need to do as they are
developing new treatments?
