Answer:
Yes, the company can expect a profit in the long term
Step-by-step explanation:
In this question, we are to project if a company is expected to make a profit or loss given the information in the question.
Let’s use the scenario of 50 gadgets produced.
1 is expected to be faulty, while 49 is thus expected to work perfectly.
Now, on this 49 sold, there is an expectancy of $3 profit. Hence, this means that for a batch of 50 gadgets produced, the amount of expected profit will be 49 * 3 = $147
The amount that would be used to repair the faulty unit is $80. If we subtract this from the total expected profit, we have $147-$80 = $67
Hence, per 50 gadgets sold, a total of $67 in profit is to be expected
This means profit is expected in the long tey
Answer:
The standard deviation of the sample mean is
Step-by-step explanation:
From the question we are told that
The mean is ![\= x = 60](https://tex.z-dn.net/?f=%5C%3D%20x%20%20%3D%20%2060)
The standard deviation is ![\sigma = 21](https://tex.z-dn.net/?f=%5Csigma%20%20%3D%20%2021)
The sample size is ![n = 60](https://tex.z-dn.net/?f=n%20%20%3D%20%2060)
Generally the standard deviation of the sample mean is mathematically represented as
![\sigma _ {\= x } = \frac{\sigma }{\sqrt{n} }](https://tex.z-dn.net/?f=%5Csigma%20_%20%7B%5C%3D%20%20x%20%7D%20%3D%20%20%5Cfrac%7B%5Csigma%20%20%7D%7B%5Csqrt%7Bn%7D%20%7D)
substituting values
![\sigma _ {\= x } = \frac{ 21 }{\sqrt{60} }](https://tex.z-dn.net/?f=%5Csigma%20_%20%7B%5C%3D%20%20x%20%7D%20%3D%20%20%5Cfrac%7B%2021%20%7D%7B%5Csqrt%7B60%7D%20%7D)
![\sigma _ {\= x } = 2.711](https://tex.z-dn.net/?f=%5Csigma%20_%20%7B%5C%3D%20%20x%20%7D%20%3D%202.711)
