I assume you mean a Z score.
Z = (score-mean)/SD
Z = (score-mean)/SD
Raw score = (Standard score * Standard deviation) + Mean
In this case, the standard score is given as 2.429, the standard deviation is 7, and the mean is 57.
Plugging in these values into the formula, we can calculate the raw score as:
Raw score = (2.429 * 7) + 57
Simplifying the expression:
Raw score = 16.003 + 57
Calculating:
Raw score ≈ 73.003
Therefore, the student's raw score on the exam would be approximately 73.003.
