Question

Quizplus · Accepted Answer

The variance of an exponential distribution with parameter λ is equal to 1/λ^2. Therefore, if the variance is 0.5, then λ^2 = 2, which means λ = √2. So the parameter is not equal to 1, which contradicts the given information.

If the Random Variable X Is Exponentially Distributed With λ\lambdaλ = 2 Parameter, Then the Variance of the Distribution Is
