Answer:
And we can find this probability using the normal standard distribution table or excel and we got:
Explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the expected return, and for this case we know the distribution for X is given by:
Where 
and 
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the normal standard distribution table or excel and we got:
Answer:
$816
Explanation:
Calculation for Dunbar Incorporated Ending inventory
Formula for Ending inventory units using FIFO method:
Ending inventory units = Beginning balance + Purchase -sales
Leg plug in the formula
490+410 - 600
= 300units
Calculation for Ending inventory
Ending inventory = 300*2.72
= $816
Therefore the Ending inventory assuming FIFO method is use would be $816
