  • exponitial distributions on exam p

    which exponitital distribution do they use on the exams? (1/x)e^-(a/x) or xe^-(ax)??

    Either one -- they are equivalent. It can appear in either form, and if you remember one, you can easily convert to the other.

      If x is the variable, then neither of these represents exponential
      distribution. So you probably need to explain yourself.

      In any case, there is no difference between exponential distribution in which its parameter is its mean, or the reciprocal of its mean -- different convention amounts to a choice of parameter, but not the distribution itself.
