The distribution of molecular kinetic energy at two temperature is as shown in the following graph. 

Which of the following conclusions are correct? 

The graph is not according to the Maxwell-Boltzmann energy distribution law

The number of molecules with energy ${\mathrm{E}}_{\mathrm{a}}$ is the mean of all temperatures 

The number of molecules with energy ${\mathrm{E}}_{\mathrm{a}}$ or greater is proportional to the shaded area for each temperature 

The number of molecules with energy ${\mathrm{E}}_{\mathrm{a}}$ or less is proportional to the shaded area for each temperature
