Find difference in average absorption time for the two drugs

Reference no: EM13200621

Two pain relief drugs are being considered. 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 blood stream was 1x= 24 minutes with standard deviation s1 = 3 minutes. For the second drug, a random sample of 10 doses showed the average time required for absorption was 2x= 29 minutes with standard deviation s2 = 4.9 minutes. Assume the absorption times follow a normal distribution. Find a 90% confidence interval for the difference in average absorption time for the two drugs. Does it appear that one drug is absorbed faster than the other (at the 90% level)? Explain
