Answer 1

The z-score for an SAT score of 720 is 1.7391, indicating it is above average.

Step-by-step explanation:

To calculate the z-score for an SAT score of 720, we can use the formula: z = (x - mean) / standard deviation. Plugging in the values, we get z = (720 - 520) / 115 = 1.7391.

This means that a score of 720 is approximately 1.7391 standard deviations above the mean. In other words, it is a relatively high score compared to the average.
