A random sample of data has a mean of 78 and a variance of 49. a. Use Chebychev's theorem to determine the percent of observations between 57 and 99. b. If the data are mounded, use the empirical rule to find the approximate percent of observations between 57 and 99. a. Using Chebychev's theorem, the portion of the data which are between 57 and 99 is at least %. (Round to one decimal place as needed.)
