CAS Exam MAS-I Spring 2018, Question 16
Study guide: Exam MAS-I
Suppose that a random draw is made from a normal distribution N(\mu, \sigma^2), where \sigma is known to be 2.
The normal distribution density is given by:
f(x; \mu, \sigma) = \frac{1}{\sigma\sqrt{2\pi}}\, e^{-\frac{(x-\mu)^2}{2\sigma^2}}, \qquad -\infty < x < \infty
Calculate the Fisher information of \mu.
- A) Less than 0.2
- B) At least 0.2, but less than 0.4
- C) At least 0.4, but less than 0.6
- D) At least 0.6, but less than 0.8
- E) At least 0.8
