Continuous Probability Spaces

Continuous Probability Spaces. ? is not countable. Outcomes can be any real number or part of an interval of R , e.g. heights, weights and lifetimes. Can not assign probabilities to each outcome and add them for events. Define ? as an interval that is a subset of R .

The Standard Normal Distribution

The Standard Normal Distribution. Standard Normal Density Curve. The standard normal distribution has a mean = 0 and a standard deviation = 1 Values on the x-axis are the number of standard deviations from the mean, called z-scores Interactive Applet: www.whfreeman.com/sta
