Question

A school requires an entrance exam score that is in the top 3% of the population in order to be accepted. If an entrance exam has a mean of 500 and a standard deviation of 55, what is the minimum qualifying score to be accepted at the school?A.) 396.05B.) 396.60C.) 603.40D.) 603.95

Answer 1

603.40

Explanation:

Minimum required score = Mean + ( Z-score * Standard deviation )

Given:

Mean = 500

Z score of 3 (0.03%) = 1.88

Standard deviation = 55

therefore

Minimum required score = 500 + (1.88)(55)

Minimum required score = 603.40
