Understanding Probability, and that life or death often depends on a diagnosis. When necessary information for a desired calculation is unknown or unknowable, we can still calculate probable answers. The mathematics of probability has been devised to make these calculations as reliable as the incomplete input data permit them to be.杀人 发表于 2025-3-27 13:18:55
Using the Normal Distribution, observation belongs to the set with a given mean and standard deviation or whether it belongs to some other set. These judgments rely on integration of the Gaussian function. In this book, of course, we do our integration by computer, a technique that is discussed at some length near the end of the chapter.织物 发表于 2025-3-27 16:33:39
Understanding Experimental Error and Averages,best estimate of the accuracy of the measurements. Thus, if we say a steel rod is 27 cm long, we are not committing ourselves to the degree of accuracy that we are if we say that it is 27.032 cm long. By one convention, the last digit is taken to be an uncertain digit; hence, 27 cm implies that theoncologist 发表于 2025-3-27 19:11:32

Using the Poisson Distribution,leus. The probability of such a disintegration is so small that an observer watching a single ..U nucleus for the entire time the earth has existed would have only a 50–50 chance of seeing it disintegrate. The number of atoms in a milligram of ..U is so huge, however, that numerous atoms decay in onANT 发表于 2025-3-28 10:19:10
Using the Normal Distribution,r, we shall develop a relationship between the Gaussian distribution and the mean and standard deviation treated earlier. Once we know the population mean and standard deviation of a randomly distributed continuous variable, we can predict the probability that future measurements will fall within an讽刺 发表于 2025-3-28 11:33:43
