If the mean of a positively skewed distribution is 126, which of these values could be the median of the distribution?

1 answer:

7 0

The mean is larger than the median in a positively skewed distribution
so the median is less than the mean in a positively skewed distribution
118

(x^3+3x^2+3x+1)(x)=\stackrel{y}{0}\implies x^4+3x^3+3x^2+x=y$
