Business: Compute the following probabilities: a. If Y is distributed N (-8,9), Pr (Y≤-12) = —— . (Round your response to four decimal places.) b. If Y is distributed N (-4,9), Pr (Y -1) = ——. (Round your response to four decimal places.) c. If Y is distributed N (40,25), Pr (34≤Y≤44) = ——. (Round your response to four decimal places.)

a. 0.3300 b. 0.3707 c. 0.1584

Explanation:

If X is distributed N( $\mu,\sigma^2$ ) [Normal distribution], then Z-score = $\dfrac{X-\mu}{\sigma}$ .

a. If Y is distributed N (-8,9),

Pr (Y≤-12) $=P(\dfrac{Y-\mu}{\sigma}\leq \dfrac{-12-(-8)}{\sqrt{9}})$

$=P(Z\leq -1.33)=1-P(Z$

b. If Y is distributed N (-4,9),

Pr (Y>-1) = $=P(\dfrac{Y-\mu}{\sigma}\dfrac{-1-(-4)}{3})$

=P(Z1)=1-P(Z

c. If Y is distributed N (40,25),

Pr (34≤Y≤44) = $P(\dfrac{34-40}{5}$

P(-1.2
