Below is a line graph of monthly rainfall (in inches) in Seattle, WA. Note that the line goes up and down, so it's obviously not a cumulative graph. Each heavy dot on the line shows the rainfall for the month written below that dot. The lines that connect the dots help you see the general month-to-month trends.

Which of the following cumulative graphs is consistent with the line graph of monthly rainfall displayed above?

You have no doubt seen a circle graph or pie chart many times. A circle graph is similar to a relative frequency plot — it shows the percentages of observations. The following graph shows the distribution of living arrangements of elderly people in the United States in 1990. Each "slice" of the pie represents the percentage of elderly people in a particular type of living arrangement. Choose the relative frequency graph most similar to the pie chart displayed below.

Below is a dot plot. The x-axis is a number line showing the average days of no rainfall in the month of January in a sample of European countries. Each dot represents the average days of no rainfall in a particular country. The plot shows, for example, 2 dots above 20, indicating two countries experience, on average, 20 days of no rainfall in January.

All of the following graphs are consistent with the data presented in the dot plot of rainfall in 25 countries, shown above, except:
