A committee has 6 members having weights (In kg) as 45, 50, 65, 72, 63, 35. Find the stander deviation

Chebyshev's theorem gives a lower bound for the area under a curve between two points that are on opposite sides of the mean and at the same distance from the mean.

Chebyshev'sTheorem : For any number 𝑘 Smaller than 1
