A standard painkiller used for patients after minor surgeries is known to bring relief in 3.5 minutes on the average (\muμ). A new painkiller is hypothesized to bring faster relief to patients. To test this hypothesis, a sample of 19 patients with minor surgeries are selected and given the new painkillers. This sample yields a mean of 2.8 minutes and a standard deviation of 1.1 minutes. Do the data provide sufficient evidence to indicate that the new painkiller indeed works...
