Passage

Based on the above data, answer the given subquestions. The probability density function of a continuous random variable

X

is given by

f_X(x, \alpha) = \begin{cases} \alpha^{-2} x e^{-x / \alpha}, & x > 0, \alpha > 0 \\ 0, & \text{otherwise} \end{cases}

Hint:

\int_0^\infty \frac{x^k}{\theta} e^{-x/\theta} dx = k! \theta^k

Let a random sample of

X

1, 2, 2.5, 2.5, 2

. Find the method of moments estimate of

\alpha

for the given sample.
