... yard waste-11%, other-13%. a. Construct a Pareto diagram displaying this information. b. Because of the size of the "other" category, the Pareto diagram may not be the best graph to use. Explain why, and describe what additional information is needed to make the Pareto diagram more appropriate. ...

... A researcher wants to estimate the difference in the means of two populations. A random sample of 40 items from the first population results in a sample mean of 433 with a population standard deviation of 112. A random sample of 50 items from the second population results in a sample mean of 467 wit ...

... deviation is a curious thing. When we calculate the mean for a sample the best guess of the mean for the population is the same value. However, the standard deviation doesn't work like that. When we calculate the standard deviation for a sample, it is likely to be an underestimate of the standard de ...
