... some fixed t0 hours from when it was first put into use. We can show that P (X ≥ t+t0 | X ≥ t0 ) = P (X ≥ t). This means that the exponential distribution has a memoryless property. ...

... Understand which “average” is the appropriate one to use in a given situation. For example: median is appropriate to use when discussing family income, since a few high incomes (outliers) would raise the mean. Median would be a better representation of what the “average” family earns. Understand t ...

... they’re spread out and bunched up, and between the minimum x1 and the maximum xn you observed. Assuming that you don’t want a “mass” of probability sitting directly on x1, you’d specify c1 = 0 and then cj = (j – 1)/(n – 1) for j = 2, 3, . . ., n. ...

... You have been asked to sample a forest tract using 0.25 hectare plots to estimate the mean tree height (meters). The tract contains three distinct vegetation types. You want to show how stratification can improve your estimate. (Obviously in a real sampling situation the raw population data would be ...
