Answer: 93 units should be ordered.
Step-by-step explanation:
Since we have given that
Standard deviation = 4
Average = 30 units
Number of weeks in order interval = 3
Desired service level = 97.5%
Number of units on hand = n = 43
So, the expected value would be
![E[x]=30\times (3+1)+1.96\times 4\sqrt{3+1}-43\\\\E[x]=30\times 4+1.96\times 4\times 2-43\\\\E[x]=120+15.68-43\\\\E[x]=92.68\approx 93](https://tex.z-dn.net/?f=E%5Bx%5D%3D30%5Ctimes%20%283%2B1%29%2B1.96%5Ctimes%204%5Csqrt%7B3%2B1%7D-43%5C%5C%5C%5CE%5Bx%5D%3D30%5Ctimes%204%2B1.96%5Ctimes%204%5Ctimes%202-43%5C%5C%5C%5CE%5Bx%5D%3D120%2B15.68-43%5C%5C%5C%5CE%5Bx%5D%3D92.68%5Capprox%2093)
Hence, 93 units should be ordered.
The neither of the statement is not from the least to greatest.
According to the statement
We have to find that the order of the numbers from least to the greatest.
So, For this purpose, we know that the
The order of an element in a group is the smallest positive power of the element which gives you the identity element.
From the given information:
We have to find the statement which represent the numbers in order from least to greatest.
And we know that the square root of 8 is 2.82.
then
A) 2.31, 2, √8
2.31, 2, 2.82
this is not from least to greatest.
Then
B) √8, 2, 2.31
2.82, 2, 2.31
This is from greatest to least.
C) 2,√8, 2.31
2,2.82, 2.31
This is not from least to greatest
D) √8, 2, 2.31
2.82, 2, 2.31
This is not from least to greatest
So, The neither of the statement is not from the least to greatest.
