<span>Well, your costs per title have decreased from:
$780/7 = $111.43
to:
$1080/12 = $90
That represents a decrease in costs of almost 20%.
Then. taking the change in titles processed per dollar of cost (the reciprocals of previous calculations), means that total productivity has increased by around 23.8%. Are you calculating labor productivity as including overhead? Because then the answer is 23.8%.</span>
Answer:
B) $1.40 per machine hour
Explanation:
Total machine hours = 29,000 + 48,000 = 77,000
Predetermined overhead allocation rate = Total estimated overhead costs / Total estimated quantity of the overhead allocation base
= $108,000 / 77,000 machine hours
= $1.40 per machine hour
Answer:
13%
Explanation:
The appropriate formula to use is as shown below:
Standard Deviation = 
Where ∑ is the summation symbol,
f is the frequency (in this sample, the probability expressed in decimal),
x is the expected return,
y is the mean return.
The formula for y, the mean return, is as follows:
y =
.
All computations are attached.
From the computation,
the mean return = 8.876%
the standard deviation of returns = 12.7377% = 13%
