1. Let a random sample of size 17 from a normal population for which both mean μ and variance σ2 are unknown yield x = 3.12 and s2 = 1.04. Determine a 99% con?dence interval for μ.

2. A random sample from a normal population yields the following 25 values:

90	87	121	96	106 107 89	107 83 92
117	93	98	120	97 109 78	87 99 79
104	85	91	107	89
