Answer:
Lorenzo's score on exam was 75.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 61
Standard Deviation, σ = 8
We are given that the distribution of test score is a bell shaped distribution that is a normal distribution.
Formula:
![z_{score} = \displaystyle\frac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z_%7Bscore%7D%20%3D%20%5Cdisplaystyle%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
z-score = 1.75
We have to find the value of x.
Putting values, we get
![1.75 = \dfrac{x - 61}{8}\\\\x = 1.75(8) + 61\\x = 75](https://tex.z-dn.net/?f=1.75%20%3D%20%5Cdfrac%7Bx%20-%2061%7D%7B8%7D%5C%5C%5C%5Cx%20%3D%201.75%288%29%20%2B%2061%5C%5Cx%20%3D%2075)
Thus, Lorenzo's score on exam was 75.
