Explanation:
To find the student's test score given the mean, standard deviation, and z-score, we can use the formula for calculating a raw score from a z-score: X = Mean + (Z-score * Standard Deviation )
Given:
Mean = 83.2
Standard Deviation = 4.65
Z-score = 2.43
Substitute the values into the formula:
X = 83.2 + (2.43 * 4.65 )
X = 83.2 + 11.2695
X = 94.4995
Rounded to one decimal place, the student's test score is 94.5.
None of the given options is answer.
