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.
<u>Answer:</u> Option 1 and Option 5

In mixed economies under the government regulation most of the production is done by private ownership. There is very little government intervention. The main aim of the government intervention is to make sure that the private business activities comply with the law of the country.
