Question

A woman is told that her weight has a standard score ( z z ‑score) of − 1.5 . −1.5. This means that:

Answer 1

Answer:

a. her weight is 1.5 standard deviations below average

Explanation:

Data provided in the question:

z score of the weight of the woman = - 1.5

Now,

The relation with the actual value and the z score is given as

x = Average + ( z × Standard deviation )

now,

substituting the value of z = - 1.5

We have

x = Average - 1.5 ×  Standard deviation

Hence,

z score = -1.5 means a. her weight is 1.5 standard deviations below average.
