QUESTION:
If, as in Exercise 4.19, Y has distribution function
\(F(y)=\left\{\begin{array}{ll}
0, & y \leq 0, \\
\frac{y}{8}, & 0<y<2, \\
\frac{y^{2}}{16}, & 2 \leq y<4, \\
1, & y \geq 4,
\end{array}\right.\)
find the mean and variance of Y.
ANSWER:Step 1 of 3
We have random variable Y with the distribution function:
\(F(y)=\left\{\begin{array}{ll}
0, & y \leq 0, \\
\frac{y}{8}, & 0<y<2, \\
\frac{y^{2}}{16}, & 2 \leq y<4, \\
1, & y \geq 4,
\end{array}\right.\)
We need to find mean and variance of of Y.
