university hospitals. Of the 27126 claims evaluated, 15012 were

the share price of one of their bond funds had very little
variability. The report shows the average price as $17.00 with a
variance of 0.11. One of the investors wants to investigate this

Recall that Benford's Law claims that numbers chosen from very
large data files tend to have "1" as the first nonzero digit
disproportionately often. In fact, research has shown that if you
randomly draw a number from a very large data file, the probability
of getting a number with "1" as the leading digit is about 0.301.
Now suppose you are an auditor for a very large corporation. The
revenue report involves millions of numbers in a large computer
file....

1. A city official claims that the proportion of all commuters
who are in favor of an expanded public transportation system is

they support an expanded public transportation system. Test the
official’s claim at α = 0.05.
2. A survey of 225 randomly chosen commuters are asked...
