Find the probability that it will take on a value within two standard deviations of the mean and compare this probability with the lower-bounded provided by Chebyshev's theorem. Let σ be the standard deviation and μ be the mean. WebA data set contains the n = 20 observations The values x and their frequencies f are summarized in the following data frequency table. x − 1 0 1 2 f 3 a 2 1 The frequency of the value 0 is missing. Find a and then sketch a frequency histogram and a relative frequency histogram for the data set.
WebAccording to Chebyshev’s inequality, the probability that a value will be more than two standard deviations from the mean ( k = 2) cannot exceed 25 percent. Gauss’s bound is 11 percent, and the value for the normal distribution is just under 5 percent.
