(C) The formula for the mean using the step-deviation method is given by:$\bar{x} = A + \left( \frac{\Sigma f_{i} u_{i}}{\Sigma f_{i}} ight) 	imes c$Given values:$A = 62.5$,$\Sigma f_{i} u_{i} = -13$,$\Sigma f_{i} = 100$,$c = 15$Substituting these values into the formula:$\bar{x} = 62.5 + \left( \frac{-13}{100} ight) 	imes 15$$\bar{x} = 62.5 + (-0.13) 	imes 15$$\bar{x} = 62.5 - 1.95$$\bar{x} = 60.55$

For a given frequency distribution,$\Sigma f_{i} u_{i} = -13$,$n = \Sigma f_{i} = 100$,$A = 62.5$ and $c = 15$. Then,mean $\bar{x} = \dots$
