Compute the weighted variance.

1	WeightedVariance(x, weights = NULL, na.rm = FALSE)

`x`	a numeric vector.
`weights`	a numeric vector of weights for `x`.
`na.rm`	a logical if NA should be disregarded.

wt=c(1.23, 2.12, 1.23, 0.32, 1.53, 0.59, 0.94, 0.94, 0.84, 0.73)
x = c(5, 5, 4, 4, 3, 4, 3, 2, 2, 1)

WeightedVariance(x, wt)
