Answer:
Equivalent units
Materials 10,200
Covnersion Cost 9, 100
Explanation:
The equivalent units will be calcualte as follow:
transferred out
ending x completion
<u> (beginning x completion) </u>
Equivalent units
<u>Materials</u>
9,000 + 3,000 x 80% - 2,000 x 60% = 10,200
<u>Conversion Cost</u>
9,000 + 3,000 x 30% - 2,000 x 40% = 9,100
The standard deviation of sample equals: 11
Explanation:
Given:
variance of sample () = 121
no, of observations made = 441
standard deviation = ?
By using the formula:
Standard deviation (S) =
=
=
= 11
Hence the standard deviation is equal to 11.
Answer:
the Expected rate of return will be 8.2%
the variance will be 0.001296
Explanation:
We will calculate the Expected Rate of Return which is the sum of the wieghted return based on their probabilities:
return of 0.15 probability 20% = 0.03
return of 0.07 probability 70% = 0.049
return of 0.03 probability 10% = 0.003
expected return = 0.082 = 8.2%
Now to calculate the variance we do:
∑(rk-ERR)^2 x pk
The sum of the difference between the expected rate and the escenario rate, power two, and multiply by their posibility
the variance will be: 0.001296
