**What is Chebyshev’s theorem formula?**

Using Chebyshev’s Rule, estimate the percent of credit scores within 2.5 standard deviations of the mean. 0.84⋅100=84 0.84 ⋅ 100 = 84 Interpretation: At least 84% of the credit scores in the skewed right distribution are within 2.5 standard deviations of the mean.

**What is Chebyshev method?**

In numerical linear algebra, the Chebyshev iteration is an iterative method for determining the solutions of a system of linear equations. The method is named after Russian mathematician Pafnuty Chebyshev. Chebyshev iteration avoids the computation of inner products as is necessary for the other nonstationary methods.
