  When combining to random variables, X and Y, by addition, what is the mean of X+Y? What is the standard deviation of X+Y? Answer these questions for subtraction. When you multiply a random variable by a constant, like changing units from inches to centimeters, what happens to the mean and standard deviation of the random variable?

  Normal Random Variables. Definition of normal random variable ---Definition 5.6 ---We say that X is a normal random variable, or simply, that X is normally distributed, with parameters and 2 if its pdf is given by. We denote the above random variable by X~N( , 2), in which the letter N means normal.

  Combining Normal Random Variables If a random variable is Normally distributed, we can use its mean and standard deviation to compute probabilities. Any sum or difference of independent Normal random variables is also Normally distributed. Example: Mr. Starnes likes between 8.5 and 9 grams of sugar in his hot tea.
