Answer:
$43,920.
Step-by-step explanation:
We have been given that the salaries of elementary school teachers in a particular country are normally distributed with a mean of $38,000 and a standard deviation of $4,000.
We will use the normal distribution table to solve our given problem. From normal distribution table, we need to find the z-score corresponding to the top 7% or z-score corresponding to probability 93% (0.93).
From normal distribution table, we get our required z-score as 1.48.
Now, we will use z-score formula to solve for sample score as:
![z=\frac{x-\mu}{\sigma}\\\\1.48=\frac{x-38000}{4000}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%5C%5C%5C%5C1.48%3D%5Cfrac%7Bx-38000%7D%7B4000%7D)
![1.48*4000=\frac{x-38000}{4000}*4000](https://tex.z-dn.net/?f=1.48%2A4000%3D%5Cfrac%7Bx-38000%7D%7B4000%7D%2A4000)
![5920=x-38000](https://tex.z-dn.net/?f=5920%3Dx-38000)
![5920+38000=x-38000+38000](https://tex.z-dn.net/?f=5920%2B38000%3Dx-38000%2B38000)
![43920=x](https://tex.z-dn.net/?f=43920%3Dx)
Therefore, the cutoff salary for teachers in the top 7% is $43,920.
