1Q11. Chebyshev's Theorem" -The proportion of values from a data set that will fall within K standard deviations of the mean will be at least 1 1 where K is a number greater than 1. K2 ? (The constant K is not necessarily an integer.) According to the Chebyshev rule, at least (minimum) what percentage of the observations in any data set are contained within a distance of 2 standard deviations around the mean? (a) +: 68% (y): 25% (B): 75% (1) 7: 88.89% (0) : 95% (0) : 95% (m):-99.7% 2EA
