Answer:
4.53%
Explanation:
Data provided in the question:
Expected return = ∑ (Return × probability)
Thus,
Expected return = (0.06 × 22) + (0.92 × 13) + (0.02 × (-15))
= 12.98%
Now,
Probability Return Probability × (Return-Expected Return)²
0.06 22 0.06 × (22% - 12.98%)² = 4.8816
0.92 13 0.92 × (13% - 12.98%)² = 0.000368
0.02 -15 0.02 × (-15% - 12.98%)² = 5.657608
========================================================
Total = 20.5396%
Standard deviation = 
= √(20.5396)
= 4.53%
Ur at a 50:50 chance of getting right. Just guess :p
Answer:
The equilibrium number of firms is 20.
Explanation:
Q = SH × b
= 2,400 × (1/20)
= 2,400 × 0.05
= 120
Also given, Q = S / n
120 = 2,400 / n
n = 20
Answer:
$37,600 favorable
Explanation:
Variable overhead spending variance can be computed as;
= (Actual hours worked × Actual variable overhead rate) - ( Actual hours worked - Standard variable overhead rate)
= ( 18,800 hours × $77,700/12,000) - (18,800 hours × $4.5)
= [(18,800 × $6.5) - (18,800 × $4.5)]
= $122,200 - $84,600
= $37,600 favorable
It is difficult to compare relative job growth for different-sized
businesses because it is hard to determine the cutoff point at which a small
business becomes a large business. It is not easy to know the comparative job development
amongst businesses of different sizes. There are not the same parameters leading
the size of a small business versus a big business. Moreover, there is no defined
point where such a variation can be clearly identified.
