Solution

The Chebyshev rule states that for any dataset, regardless of distribution, at least 1 - 1/k^2 of the data will fall within k standard deviations of the mean.

When k=2, the formula becomes 1 - 1/(2^2) = 1 - 1/4 = 0.75 or 75%.

So, according to the Chebyshev rule, at least 75% of the data will fall within 2 standard deviations of the mean.
