Answer: 0.3
Explanation:
The Sharpe ratio is simply used by organizations and investors in order to compare the return on an investment to its risk.
From the question, we are informed that a portfolio has a 30% standard deviation generated a return of 15% last year when T-bills were paying 6.0%.
The Sharpe ratio will be:
= (15% - 6.0%)/30%
= 9%/30%
= 0.09/0.3
= 0.3
a) ( 0.8509718, 0.8890282)
b) ( 0.7255, 0.7745)
Explanation:
(a)
Given that , a = 0.05, Z(0.025) =1.96 (from standard normal table)
So Margin of error = Z × sqrt(p × (1-p)/n) = 1.96 × sqrt(0.87 × (1-0.87) / 1200)
=0.01902816
So 95 % confidence interval is
p+/-E
0.87+/-0.01902816
( 0.8509718, 0.8890282)
(b)
Margin of error = 1.96 × sqrt (0.75 × (1-0.75) / 1200) = 0.0245
So 95% confidence interval is
p+/-E
0.75+/-0.0245
( 0.7255, 0.7745)
Answer:
$635,000 and : 34%
Explanation:
Margins of safety is the difference between expected sales and the break-even point.
For Zhao, expected sales are 10,000 units
The break-even points in units = fixed cost/ contribution margin per unit
fixed costs = $429,000
Contribution margin per unit = selling price - variable costs per unit
=$187 - $122
=$65
break-even point in units = $429,000/$65
break-even point = 6600 units
Margin of safety = 10,000 - 6600 units
=3400 units
In dollars is equal to margin of safety in units x selling price
=3400 x 187
<u>=$635,000</u>
as a percent of expected sales.
=3400/10000 x 100
=0.34 x 10,000
=34%
