Answer:
Option A is correct.
0.7734.
Step-by-step explanation:
Definition: z-score indicates that how many standard deviations an element is from the mean.
It can be calculated from the following formula.
where;
z is the z-score,
X is the value of the element,
is the mean, and σ is the standard deviation.
To interprets z- score:
- if a z-score < 0, it represents an element less than the mean.
- if a z-score > 0, it represents an element greater than the mean.
- if z-score = 0, it represents an element equal to the mean.
Given: z < 0.755
then,
to find the value of z, look up the standardize normal distribution to the left of a z-score.
we get
z = 0.7734
