Question
1) An engineer plans to compute a confidence interval on the true mean inner diameter of the bearing used to support the crankshaft of a particular engine. She will do this by measuring the inner diameters of a random sample of these bearings, compute X and, and then computing the interval X ±1.6450x//n, where ox is assumed to be known from past experience with these bearings. a) The confidence interval that she is computing has what probability that the true mean diameter will be included? b) Suppose that the following measurements were recorded, in mm, 30.003, 30.004, 29.998, 30.001, 29.996, 30.002 If ox is known from past experience to be 0.003 what is her confidence interval?
