Question 8-11 refer to the following setting. You should first test the hypotheses using the ANOVA procedure and write your solutions on paper. Then answer questions 8-11 based on your solutions. A consumer agency wanted to find out if the mean time taken by each of three brands of medicines to provide relief from a headache is the same. The first drug was administered to six randomly selected patients, the second to four randomly selected patients, and the third to five randomly selected patients. The following table gives the time (in minutes) taken by each patient to get relief from a headache after taking the medicine. Drug I 25 Drug II 15 Drug III 12223 44 + 39 4 58 75 38 42 19 54 65 25 47 73 52 At the 2.5% significance level, will you conclude that the mean time taken to provide relief from a headache is the same for each of the three drugs?
