9. Two pain relief drugs are being considered. Drug 1 has shown in the past to have a standard deviation = 4 minutes. A random sample of 8 doses of the first drug showed that the average amount of time required before the drug was absorbed into the bloodstream was = 24 minutes. For the second drug, the historical data indicated a standard deviation o, = 3.9 minutes. A random sample of 10 doses showed the average time required for absorption was =29 minutes. Assume the absorption times follow a normal distribution. %3D Should you use the Z-Distribution or T-Dstribution in determining a confidence interval in this problem? Explain. a. Find a 95% confidence interval for the difference in average absorption time for the two drugs. b. Does it appear that one drug is absorbed faster than the other (at the 95% level)? Explain. с.
