null | Given the following distributions:
- $X$ - $N(\mu, \sigma^2)$, where $\mu = 2$
- $Z = \frac{X-2}{\sigma}$
- $Y = X + Z$, find the distribution of $Y$.
Attempt at solution:
Taking the CDF: $$ F_Y(y) = P(Y \leq y) = P(X+Z \leq y) = P\left(\frac{X-2}{\sigma} \leq \frac{y-2}{\sigma}\right) = P(Z \leq \frac{y-2}{\sigma})... | None | null | null | null | null | null |
