The following is a histogram showing the distribution per year of the cumulative property damage caused by tornadoes over the period 1950 to 1999 in each of the 50 states and Puerto Rico. The data are in millions of dollars, and the class intervals are 0 to < 10, 10 to < 20, and so forth. The percent of the data with average property damage of under $20M dollars is about:
Data is in the attachment below.
Solution
The frequency below 20 is = 25+6
Total frequency = 50
The percent of the data with average property damage of under $20M dollars is about: = 31/50 = 62%
