2 ![\sigma = 16](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%2016)
3 ![\mu_x = 100](https://tex.z-dn.net/?f=%5Cmu_x%20%20%3D%20%20100)
4 ![\sigma _{\= x } = 2.309](https://tex.z-dn.net/?f=%5Csigma%20_%7B%5C%3D%20x%20%7D%20%3D%202.309)
Step-by-step explanation:
From the question
The population mean is ![\mu = 100](https://tex.z-dn.net/?f=%5Cmu%20%20%3D%20100)
The standard deviation is ![\sigma = 16](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%2016)
The sample mean is ![\mu_x = 100](https://tex.z-dn.net/?f=%5Cmu_x%20%20%3D%20%20100)
The sample size is ![n = 48](https://tex.z-dn.net/?f=n%20%20%3D%2048)
The mean standard deviation is ![\sigma _{\= x } = \frac{\sigma }{\sqrt{n} }](https://tex.z-dn.net/?f=%5Csigma%20_%7B%5C%3D%20x%20%7D%20%3D%20%20%5Cfrac%7B%5Csigma%20%7D%7B%5Csqrt%7Bn%7D%20%7D)
substituting values
![\sigma _{\= x } = \frac{16 }{\sqrt{48} }](https://tex.z-dn.net/?f=%5Csigma%20_%7B%5C%3D%20x%20%7D%20%3D%20%20%5Cfrac%7B16%20%7D%7B%5Csqrt%7B48%7D%20%7D)
![\sigma _{\= x } = 2.309](https://tex.z-dn.net/?f=%5Csigma%20_%7B%5C%3D%20x%20%7D%20%3D%202.309)
Answer: A) 151 units
Step-by-step explanation:
We would apply the formula which is expressed as
N = (FC + OP)/[(R - VC)/TU]
Where
N represents the number of helicopters that must be sold.
FC represents the fixed cost
OP represents the operating income required.
R represents revenue
VC represents variable cost
TU represents the total number of units sold.
From the information given
FC = 350000
OP = 320000
R = 840000
VC = 260000
TU = 130
Therefore,
N = (350000 + 320000)/[(840000 - 260000)/130]
N = 670000/4461.54
N = 151 units rounded up to the nearest whole number
