1.5 or 1 1/2 in. On the map equals24 miles
Z-score formula is z=(x-m) / sd
x = data value
m= mean
sd = standard deviation
z= (82-78.2) / 6.7
=0.567
=0.57
The order you apply the adjustments does make a difference because the percents that are applied will be applied to different amount.
For example, 80% of 100 = $80. The price would be $180.
Decreasing this by 25% 25% of 180 = $45; 180-45 = $135.
25% of 100 is not the same as 25% of 180.
