... Range = R = largest data value - smallest data value The range is not resistant because it is affected by extreme values in the data set. A2. Variance and Standard Deviation Variance is based on the deviation about the mean. Since the sum of deviation about the mean is zero, we cannot use the averag ...

... b. Based on the confidence interval in part a, can you conclude that there is a difference in the two binomial proportions? Explain. 2. Suppose you wish to estimate a population mean based on a random sample of n observations and prior experience suggests that σ = 12.7. If you wish to estimate µ to ...

... all passwords. Now any subset A of guards can log in, if they have all the passwords, that is if ∪i∈A Xi = S. Design a fail-safe system for 5 guards with as few passwords as possible. This means two things, design a fail-safe system for 5 guards with k passwords for some k, and prove that all fail-s ...
