c. How far away from the mean it is and in what direction

d. How far away from the standard deviation it is and in what direction

Answer 1

Solution:

A z-score tell us about the how far away from the mean it is and in what direction.

Explanation:

* z- score reperesents how many standard deviation a given measurement deviates from the mean.

* It indicates how much a given value differs from the standard deviation.

*The Z-score, or standard score, is the number of standard deviations a given data point lies above or below mean.

*The positive value of z-score idicates the score are above the mean and negative value indicates the score are below the mean.

So correct answer is option C i.e, How far away from the mean it is and in what direction
