... D) negatively skewed 71. A disadvantage of using an arithmetic mean to summarize a set of data is A) The arithmetic mean sometimes has two values B) It can be used for interval and ratio data C) It is always different from the median D) It can be biased by one or two extremely small or large values ...

... with probability (power) .90, when the true 95th percentile is 20ppm. On the basis of past data or based on data from a similar workplace, suppose the value of the geometric SD exp(σ) is guessed to be 2.015ppm. Then δ ∗ = (ξp0 − ξp )/σ = (ln(50) − ln(20))/ ln(2.015) = 1.308. Since we are computing t ...

The process of finding a confidence interval for a median is based on one simple fact: the probability that a single number picked at ran ...
