Answer:
A. 0.3204 B. $14.669
Explanation:
Mean = 8.9 SD = 4.5
Required probability = P (X >/= 550/50)
P(X>/=11) = 1 - P[(X - mean/SD) < (11 - mean)/SD]
= 1 - P(Z < (11-8.9)/4.5)
P(X>/=11) = 1 - P(Z < 0.4666667)
Using Excel NORMDIST(0.4666667,0,1,1)
P(X>/=11) = 1 - 0.6796 = 0.3204
The probability that she will earn at least $550 = 0.3204
b. P
(
X > x
) = 0.10
1 − P
(
X − mean)/SD ≤ (x − mean)
/SD = 0.10
P
(
Z ≤ z
) = 0.90
Where,
z = (x − mean
)/SD
Excel function for the value of z:
=NORMSINV(0.9)
=1.282
Hence (x - mean)/SD = 1.282
= (x - 8.9)/4.5 = 1.282
x = (1.282*4.5) + 8.9
x = 14.669
He earns $14.669 on the best 10% of such weekends.
Answer:
Thailand:
Opportunity cost of computers = 300/20 = 15 tons of rice
US:
Opportunity cost of computers = 800/100 = 8 tons of rice
US has a comparative advantage in production of computers
Absence of trade:
Thailand consumes 150 tons of rice, it can consume = (300 - 150)/30 x 2 = 10 computers
US consumes 50 computers, it can consume = 400 tons of rice
After trade :
10 computers exchanged for 120 tons of rice
Thailand continues to consume 150 tons of rice, it will consume = 12 computers (=10 + 30/15)
US continues to consume 50 computers, it will consume = 440 tons of rice (=120 + 40 x 8)
Both would accept the proposal as both are better off with trade
