Chebyshev's Rule

Practice: For the following data set, at least what percent of observations would you expect to lie within 6.16 and -.16?

Practice: Referring to Practice 1, between what two values would you expect at least 8/9 of the observations to lie?

Practice: Referring to Practice 1, between what two values would you expect 84% of observations to lie?

Practice: Assuming that a particular data set has a mean and variance of 100 and 144, respectively, at least what percent of observations would you expect to see between 88 and 112?

Practice: Referring to Practice 4, what is the probability of finding an observation that lies between 82 and 118?
