Access the data about worldwide volcanic eruptions, which are available at MyMathLab and at the Pearson Downloadable Student Resources for Math & Stats website.
a. Construct a pie chart of the countries where volcanic eruptions occurred. In which three countries did almost half of the volcanic eruptions occur?
b. Construct a histogram of the numbers of deaths, beginning with lower class limit 0 deaths and class width 1000 deaths.
c. Describe the shape of the death distribution.
d. Which is a better measure of the center for the death distribution, the mean or the median? Explain.
e. Find and compare the mean and the median of the death distribution. Why is one value so much larger than the other?
f. What does the median number of deaths tell you about this situation?
