The… 0. Chapter 07 - Sampling Distributions. Because we change the random variable from "X = the number of shots" to "Y = the net gain" and Y = 10 X - 15 where 10 = the gain by shot and 15 = the cost by game (containing 2 attempts). The sum or difference of + Section 6.2 Transforming and Combining Random Variables In this section, we learned that… Adding a constant a (which could be negative) to a random variable increases (or decreases) the mean of the random variable by a but does not affect its standard deviation or the shape of its probability distribution. TRANSFORMING RANDOM VARIABLES . T. is.
