... C1 and C2 are mutually exclusive because no individual in C1 can also be in C2. C1, C3 and C4 are collectively exhaustive because everyone must be in at least one of these classes. e) The mean, median and mode have something in common as to what they measure, which they do not share with , say, the ...

... 19. An airplane is only allowed a gross passenger weight of 8000 kg. If the weights of passengers traveling by air between Toronto and Vancouver have a mean of 78 kg and a standard deviation of 7 kg, the approximate probability that the combined weight of 100 passengers will exceed 8,000 kg is: a) 0 ...

chi-square: testing for goodness of fit
... a straight line) a slope and an intercept. Φ is proportional to (or in some cases equal to) a statistical measure called χ2 , or chi-square, a quantity commonly used to test whether any given data are well described by some hypothesized function. Such a determination is called a chi-square test for ...
