Question

The error involved in making a certain measurement is a continuous rv X with the following pdf. f(x) = 0.09375(4 − x2) −2 ≤ x ≤ 2 0 otherwise
Compute
P(X < −1.1 or X > 1.1).
(Round your answer to four decimal places.)

Answer 1

You need to compute
\[
\int_{-2}^{-1.1} f(x) dx + \int_{-1.1}^2 f(x) dx
\]

Answer 2

thanx a lot :)
