Normal distributed random variable – has a PDF or relative frequency histogram shaped like a normal curve. Standard normal – normal PDF with mean of 0 and standard deviation of 1 (a z statistic!!) Key Concepts: Probability in a Continuous Probability Distributions: Let P(x) denote the probability that the random variable X equals x, then

Aug 27, 2013 · The probability model of a discrete random variable X assigns a probability between 0 and 1 to each possible value of X. A continuous random variable Y has infinitely many possible values. All continuous probability models assign probability 0 to every individual outcome. Only intervals of values have positive probability. Do #21, 23, 25 page ...
