If the Random Variable X Is Exponentially Distributed, Then Which

Short Answer

If the random variable X is exponentially distributed, then which of the following statements best describes the mean of X? $\begin{array}{|l|l|}\hline A&\text { The mean of \( \mathrm{X} \) will be greater than the standard deviation of \( \mathrm{X} \). }\\\hline B&\text { The mean of \( \mathrm{X} \) will be smaller than the standard deviation of \( \mathrm{X} \). }\\\hline C&\text {The mean of \( \mathrm{X} \) will equal the standard deviation of \( \mathrm{X} \). }\\\hline D&\text {None of these choices are correct. }\\\hline \end{array}$
