Suppose X is a continuous random variable denoting a specific measurement from a manufactured product (e.g. a volume). The quality loss from the manufacturing process leading to this product is
defined as the expected value of c(X − m)^2 , where c is a conversion constant from the deviation in the desired value for X to monetary loss for the producers.

( i.) Suppose E(X ) = m and V (X ) = σ^2 . Determine the quality loss for this process.

(ii.) Suppose E(X ) = µ and V (X ) = σ^2 . Again, determine the quality loss for this process.

I have no idea how to start this! Please help.
