2.31 standard deviation above the mean.

Explanation:

We have been given that a successful basketball player has a height of 6 feet 33 ​inches, or 191 cm. based on statistics from a data​ set, his height converts to the z score of 2.31.

We know that z-score of a data point tells how many standard deviations above or below is a data point from mean.

Since our given score is positive 2.31, therefore, the height of the basketball player is 2.31 standard deviations above the mean.

Answer 2

The correct answer is:

2.31.

Explanation:

A z-score is a measure of how many standard deviations above or below the mean a raw score is. Since the z-score is 2.31, his height is 2.31 standard deviations above the mean.
