Chapter 3, Problem 22E
Consider the concentration of suspended solids from Exercise 3.17. Assume that reading across, then down, gives the data in time order. Construct and interpret a time-series plot.
An important quality characteristic of water is the concentration of suspended solid material (in ppm). Table 3E.5 contains 40 measurements on suspended solids for a certain lake. Construct a normal probability plot, a lognormal probability plot, and a Weibull probability plot for these data. Based on the plots, which distribution seems to be the best model for the concentration of suspended solids?

Suppose that Sue and Bill each make a confidence interval out of the same data set, but Sue wants a confidence level of 80 percent compared to Bill’s 90 percent. How do their margins of error compare?
Suppose that you conduct a study twice, and the second time you use four times as many people as you did the first time. How does the change affect your margin of error? (Assume the other components remain constant.)
