Question

The z-scores for x values which are greater than the mean will be negative true false

Answer 1

false

Explanation:

if X is larger than mean, we will have a positive number. hence, we will have positive z-score.

example:

if X = 55, mean = 47, SD = 6,

the z-score = (55 - 47) / 6

= 8/6

= +1.33.
