What is a positively skewed distribution

In a positively skewed distribution, the mean is usually greater than the median because the few high scores tend to shift the mean to the right. ... In a negatively skewed distribution, the mean is usually less than the median because the few low scores tend to shift the mean to the left.

Step-by-step explanation:

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
