Lasers can provide highly accurate measurements of small movements. To determine the accuracy of such a laser, it was used to take 82 measurements of a known quantity. The sample mean error was 20 μm with a standard deviation of 60 μm. The laser is properly calibrated if the mean error is μ = 0. A test is made of H0 : μ = 0 versus H1 : μ ≠ 0. Find the P value?
