consumer agency wanted to find out if the mean time it takes for 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, the third to five randomly selected patients. Table 4 gives the time (in minutes) taken by each patient to get relief from a headache after taking the medicine. Compute the appropriate test using 5% significant level.
