When Lorenzo finished his exam last week, he thought the test was over. But the instructor put z-scores on each student's paper

Anarel [89]

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:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

z-score = 1.75

We have to find the value of x.

Putting values, we get

$1.75 = \dfrac{x - 61}{8}\\\\x = 1.75(8) + 61\\x = 75$

Thus, Lorenzo's score on exam was 75.
