Question

What was Nefani's z-score on the verbal section of the high school exam in 2011 if the mean score was 497 and the standard deviation was 114?

Options:
A) -0.79
B) 0.79
C) 1.23
D) -1.23

Answer 1

We cannot calculate Nefani's z-score without knowing her actual exam score. The z-score formula requires the actual score, mean, and standard deviation.

The correct answer is none of all.

Step-by-step explanation:

To calculate Nefani's z-score on the verbal section of the high school exam in 2011, you would use the formula for a z-score, which is:

z = (X - μ) / σ

Where X is the score, μ (mu) is the mean, and σ (sigma) is the standard deviation. However, the score that Nefani received on the exam is not provided in the question. Without Nefani's actual score, we cannot calculate the z-score. Therefore, we cannot determine which of the provided options (A, B, C, or D) is correct.
