The low and high estimate of number people watching the parade has to be identified for the given uncertainty, if the number of people watching the parade was estimated by the police to be 50000. Concept Introduction: Whenever a measurement is made, the significant figures in the measured quantity give the actual measurement. For this the significant figures should be recognized first. The significant figures may be non-zero digit and zero digit. But Zero may be or may not be a significant figure. The number of significant figures gives more information about the degree of uncertainty. This uncertainty is determined from the last digit. One should also note in which place the last digit appears, either in the tenth, or hundredth or thousandth place.
