Suppose that the random variable $x$ has an exponential distribution with $\theta = 1.5$. Find the mean and standard deviation of $x$.
A) $\mu " 0 ; \sigma = 1$
B) $\mu " 0 ; \sigma = 1.5$
C) $\mu " 1.5 ; \sigma = 1.5$
D) $\mu ^ { \prime \prime } 1.5 ; \sigma = 1$

Quizplus · Accepted Answer

For an exponential distribution with parameter $\theta$, the mean ($\mu$) and standard deviation ($\sigma$) are both equal to $\theta$. Therefore, with $\theta = 1.5$, both the mean and standard deviation are 1.5.
