Suppose that the 'life-time' of Disc Brake pads has a Normal distribution with a mean = 50,000 miles but with some unknown standard deviation σ. Suppose that a sample of n = 16 pads is tested for their 'life-times' yield S = 2500 as the sample estimate σ. Find the probability that the sample average X16 exceeds 49,000 miles, Pr(≥49,000) 16
