Sear Activity non in onch blank with the correct statistical test for two population is used when two sets of dnta are collected from the me source is used when independent samples n,> 30 and na > 30 are obtained from two populations. is used when independent samples ni < 30 or ng < 30 are obtained from two normally distributed populations with unknown variances but assumed to be equal. is used when independent samples ,< 30 or n2 < 30 are obtained from two normally distributed populations with known variances, is used when independent samples n; <30 or 12 < 30 are obtained from two normally distributed populations with unknown variances but assumed to be unequal. B. Test the given null hypothesis H, against the given alternative hypothesis H, using the given data. Use 5% level of significance. Assume that the samples are obtained from normal populations. 1. Ho: My = Hy versus He: My He 1 Sample 1 Sample 2 65 n = 50 X;=85 8 = 11 n2 = Ig = 80 Sy = 8 2. Ho: Hi = H2 versus H:H * 12 (Assume o =0.) Sample 1 Sample 2 12 12 = 15 X; = 15.9 X2 = 17 89 = 8 n = 31 = 1.1 3. Ho: Hi = H2 versus H:H *Hz (Assume o +07.) Sample 1 Sample 2 ng = 15 1 - 12 = 15.9 81 - 1.1 * Ij = 17 8y = 8
