Question: Suppose that a random sample consisting of 16 observations is available from the normal distribution for which both the mean 1 and the variance 21

Suppose that a random sample consisting of 16 observations is available from the normal for which both the mean Î¼1 and the variance Ïƒ21 are unknown, and an independent random sample consisting of 10 observations is available from the normal for which both the mean Î¼2 and the variance Ïƒ22 are also unknown. For each constant r > 0, construct a test of the following hypotheses at the level of significance 0.05:
