Question
[5] The following information was obtained from two independent samples selected from two nor-
mally distributed populations with unknown but equal variances.
Sample 1: 14 15 11 14 10 8 13 10 12 16 15
Sample 2: 17 16 21 12 20 18 16 14 21 20 13 20 13
You are interested in concluding at the 2.5% significance level that µ1 < µ2. Are you able to
conclude that? (Do not forget to state the null and alternative hypotheses). Interpret your result.
