Two injectable medications (Type A and Type B) for asthma remain in the bloodstream for many hours. Independent simple random samples of 11 subjects who were administered type A and 9 subjects that were administered type B were selected and the amount of the medication in their bloodstream was monitored and recorded. You want to test the claim that the mean time in the bloodstream is different between the two types of medication. Assume a normal distribution and do not assume that the population standard deviations are equal. These are the data for the two types of medication:
Type A Type B Cl = 76.3 hrs i72 = 65.1 hrs s1 = 4.5 hrs s2 = 5.1 hrs n=11 1 n2 = 9
Do the following:
a. Identify the null hypothesis and the alternative hypothesis.
b. What is the equation you would use to find the test statistic? Plug in the numbers but do not solve. For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).
