Question 1136028
the formula is z = (x - m) / s


z is the z-score
x is the raw score
m is the mean
s is the standard deviation.


since the standard deviation is in the denominator, it stand to reason that, if the numerator remains the same, then the fraction with the smallest denominator will be the largest.


that means the standard deviation of 1 will give you the highest z-score.


(x - m) is equal to 20 - 16 which makes the numbeator equal to 4.


4/8 = 1/2
4/2 = 2
4/4 = 1
4/1 = 4 *****
