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.

Explanation:
According to different researches carried out across the U.S., young adults who are between 18 and 29 years old have a total debt to $1.05 trillion. Individuals' debt who are older than 70 is $1 trillion. The average debt amount that young adults (18-29) have is $22,000 while elder people from 50 years old and on is $36,000.
Then, <em>young adults have larger accumulated debt than elders and their debt amounts are lower as well.</em>
