Answer #1

Answer : Measure twice and compare the results

Note : As in reliability testing, the probability of getting similar results repeatedly is measured to know the system is failure free. It can be done through measuring the results twice or more and comparing the results to check if it varies.

    38. In a physics experiment, two different methods were used to measure the angle of deflection when a subatomic particle collides with a certain material. Ten specimens of the material were used to compare the two methods, For each specimen, the angle of deflection was measured using both methods. For each specimen, the method used first was determined by the flip of a fair coin. The difference between the measured angles was calculated for each specimen. A test of the...
