1.Many of the continuous random variables that occur in real life are approximately normally distributed. How do you think this helps in studying real life variables?

2. Do you realize and understand the advantage of being able to convert values of an arbitrary normally distributed random variable to the corresponding values of the standard normal variable? If yes, list all the possible advantages of being able to accomplish it. If not what do you plan to do to understand why the standard normal random variable is widely used for computations involving normal distributions?
