Here we see that eastern state has maximum average spend on their K-12 students compared to western state .
Mean spent by eastern state = 12610
Mean spent by western state = 10290
Shape of both distribution is positively skewed.
Mode of both the distribution is lies between 8000 to 10000.
Eastern state spend more amount than western states.
