the equation shown is used in statistics to relate z, the z - score of a data element, to x, the value of the data element, m, the mean of the data set and d, the standard deviation of the data: z = (x - m)/d. solve the formula for m, the mean of the data set. enter your answer in the box. m =

Explanation:

Step1: Multiply both sides by d

$z\times d=\frac{x - m}{d}\times d$
$zd=x - m$

Step2: Isolate m

$m=x - zd$

Answer:

$m=x - zd$
