Answer:

A. negatively skewed

Step-by-step explanation:

Plot the values of salary against years

You will notice that;

  • The graph has a long left tail
  • The tail is longer towards the negative direction of the number line

This mean that this graph is a negative skewed graph/left-skewed distribution

In the attached sketch of the plot, join the points with a smooth curve and observe the above mentioned properties.

The x-axis scale ranges from 2000 to 2015 where 0=2000, 1=2001,2=2002......,15=2015

Hope this will give you a visual picture of the negatively- skewed distribution
