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?

. Studies are often done by pharmaceutical companies to determine the effectiveness of a treatment program. Suppose that a new AIDS antibody drug is currently under study. It is given to patients once the AIDS symptoms have revealed themselves. Of interest is the average length of time in months patients live once starting the treatment. Two researchers each follow a different set of 40 AIDS patients from the start of treatment until their deaths. The following data (in months) are...

In a clinical trial, 20 out of 881 patients taking a prescription drug daily complained of flulike symptoms. Suppose that it is known that 1.9% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 1.9% of this drug's users experience flulike symptoms as a side effect at the α=0.05 level of significance? Because np 0 (1 minus p 0) = 10, the sample size is ▼ less than or greater than...

When people take sleeping medicine they would like to go to sleep as quickly as possible. For a new sleeping drug a study was done comparing time to go to sleep with the new pill to known time to go to sleep without any pill. Previous research shows that on average without a pill people fall asleep in mean time of μ{"version":"1.1","math":"<math xmlns="http://www.w3.org/1998/Math/MathML"><mi>μ</mi></math>"} = 15 minutes with a standard deviation of σ = 10 minutes.
