Here's the formula for finding the z-score (a.k.a. standardized normal variable) of one measurement of a normal random variable :
,
where
- is the z-score of this measurement,
- is the value of this measurement,
- is the mean of the random normal variable, and

Let the length of a trout in this lake be inches.
.
- , and
- .
For this measurement, . Apply the formula to get the z-score:
.
Answer: $18.75
125 x 0.15 = 18.75
Luke = x
Jordan = 2x
Erin = 2x - 5
x + 2x + 2x -5 = 59
5x = 65
x = 13
