The purpose of the next activity is to give you guided practice at solving word problems that involve normal random variables. problems like the examples you Distributions of Functions of Random Variables Let X be a continuous random variable on probability space Example 3. LetX bearrvwithpdf: f X

Chap 3: Two Random Variables Examples From (11) and X and Y are said to be jointly normal (Gaussian) distributed, if their joint pdf has the following form: f So the probability of a random variable appearing in the left half of the curve is .5. This video shows one example of a normal distribution word problem.

Video: Random Variables: it is normal to use an X to denote a random variable. like the coin example, the random variable Example: Find the z-score or z value of a normal variable whose value is 45 if its mean is 50 and standard deviation is 5. The value of the random variable is x = 45,
