Answer: mean monthly income = $5000
====================================================
Explanation
In any normal distribution, the median and mean are the same value.
-------------
The proof is as follows:
If mean > median was the case, then the distribution would be skewed to the right (ie positively skewed). The right tail is pulled longer than the left tail. But this would contradict the symmetrical nature of the normal distribution. So mean > median must not be the case.
If mean < median, then the distribution would be skewed to the left (negatively skewed). Visually this pulls the left tail longer than the right tail. Like in the previous paragraph, this contradicts the symmetrical nature of the normal distribution. So mean < median must not be the case.
Since mean > median cannot be true, and neither can mean < median, this must indicate mean = median.
-------------
So in short, any symmetrical distribution always has mean = median and they are at the very center of the distribution.
Answer:
correct option is here B. About 14.3
Explanation:
given data
running sum of forecast errors RSFE = 500
mean absolute deviation MAD = 35
solution
we get here tracking signal that is express here as
tracking signal =
.................................1
put here value and we will get tracking signal
tracking signal = 
tracking signal = 14.3
so correct option is here B. About 14.3
Answer:
Accounting rate of return = 20.53%
Explanation:
<em>The accounting rate of return is the average annual income expressed as a percentage of the average investment.</em>
The simple rate of return can be calculated using the two formula below:
Accounting rate of return
= Annual operating income/Average investment
× 100
Average investment = (Initial cost + scrap value)/2
= 30,000/2= 15,000
Accounting rate of return = ( 3080/15,000) × 100
= 20.53%
Accounting rate of return = 20.53%
