... Section 4.6, but we’ll hit the high points below. 1. The idea is this: If a sample is really drawn from a normal distribution, then the pth percentile of the sample should match closely with the pth percentile of a truly normal population. Plotting one against the other should result in a straight l ...

... 7. (Textbook 4.92) The length of time Y necessary to complete a key operation in the construction of houses has an exponential distribution with mean 10 hours. The formula C = 100 + 40Y + 3Y 2 relates the cost C of completing this operation to the square of the time to completion. Find the mean and ...

... We have listed each in increasing order because once the numbers are chosen, we arrange them in increasing order. There are 10 sets of three numbers that can be chosen. Of these 10, the 4 sequences 1, 2, 3 and 1, 3, 5 and 2, 3, 4 and 3, 4, 5 are arithmetic sequences. Therefore, the probability that ...

... Many interesting statistical problems arise in the cases of low statistics, i.e. a small number of measurements. In those cases, Bayesian or frequentist methods usually leads to different results. In those cases, using the Bayesian approach, the choice of the prior probabilities plays a crucial role ...
