Unformatted text preview: Probability Properties Normal Distribution Standard Normal Calculations of probabilities from table - 2 - Inverse Problems Value at Risk (VaR) Sampling Distributions (Chapter 14) Sample Mean x If x is normal with mean μ and std dev σ, then the sample mean x is normal with mean μ and std dev σ/ n , where n is the # of observations in the sample. Even if x is non-normal, the sample mean x is approximately normal with mean μ and std dev σ/ n when n is large. Calculating probabilities Sample Proportion p p is approximately normal with mean p (true proportion) and std dev n p p ) 1 ( , where n is the # of observations in the sample.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
