The document discusses a hypothesis test comparing the recovery times of patients treated with two different medications for severe bladder infections. It assumes normal populations with equal variance and tests whether the first population mean is smaller than the second, using significance levels of 5% and 1%. The null hypothesis states that the two population means are the same.

- 1. The following data. recorded in days, represent the length of time to recovery for patients randomly treated with one of two medications to clear lip severe bladder infections. Assume that the data come from normal populations with equal variance. Test the hypothesis that the two population means are the same against the alternative that the first mean is smaller. Use 5% and 1% significance levels. Solution H0= The 2 population means are the same. H1= The first mean is smaller
