1.The assumption that the period is independent of the amplitude is only approximately true. Suppose the period changes by 2½% when starting at 30° instead of when starting at 10°. Suppose that for the single swing measurements of a pendulum had an average period of 1.00 s, with a standard deviation of 0.03 s and a standard error of 0.01 s. How many repetitions of the single period measurement would have to be made of the 30° swings to say that this difference was statistically significant? i.e., how many swings on average would have to be measured before the SET failed?
