The data value of 9770 corresponds to the 41st percentile if the mean population is 10000 and the standard deviation is 1000.
What is an equation?
An equation is an expression that shows the relationship between two or more variables and numbers.
The z score is given by:
z = (raw score - mean)/standard deviation
Let us assume the mean population is 10000 and the standard deviation is 1000.
The 41st percentile corresponds with a z score of -0.23, hence:
-0.23 = (x - 10000)/1000
x = 9770
The data value of 9770 corresponds to the 41st percentile if the mean population is 10000 and the standard deviation is 1000.
