    Mean and Standard deviation.

    Just wondering if anyone could point me in the right direction, I need to decide what distribution method to use.

    'Recent work at a particular environmental monitoring station shows thath ourly concentrations of an airborne pollutant has mean 26.01 ml/m^3 and standard deviation 7.342ml/m^3.In selecting a suitable distribution note that, under exceptional environmental conditions, concentrations of pollutants can be very large.'

    Without more information there is no way to say anything about the distribution. But you could try the log-normal if you must.
