Answer:
a: 12.8%
Explanation:
Standard Deviation would be calculated with the probability approach since there is probability given in the question.
- Formula of Standard Deviation and the solution is given in the pictures below.
- Although ERR the required part to calculate Standard Deviation is calculated in the text.
Calculating ERR:
ERR= Sum of Probabilities × Rate of returns.
In our question = ERR= 0.2 × 30% + 0.5 × 10% + 0.3 × (-6%) = 0.128 = 12.8%
Thus, by putting all the values in the formula you will get the answer 12.8%.

Answer:
$3,799
Explanation:
The total bill amount is
Before that The computation of the fixed cost and the variable cost per minute by using high low method is computed
Variable cost per minute = (High bill cost - low bill cost) ÷ (High minutes - low minutes)
= ($4,500 - $2,630) ÷ (480 - 160)
= $1,870 ÷ 320
= $5.84
Now the fixed cost equal to
= High bill cost - (High minutes × Variable cost per minute)
= $4,500 - (480 × $5.84)
= $4,500 - $2,803
= $1,697
Now the total bill would be
= Fixed cost + expected minutes × variable cost per minutes
= $1,697 + 360 × $5.84
= $1,697 + $2,102
= $3,799
