The graph summarizes data on a sample of 100 automobiles requiring warranty service within one year of purchase. Each automobile required service in exactly one of seven categories. For each category, the frequency is the number of automobiles in the sample requiring service in that category; the cumulative frequency is the total number of automobiles in the sample requiring service in that category or in any of the categories to the left in the graph. In the graph, the frequency scale is on the left and the cumulative frequency scale is on the right.
From each drop-down menu, select the option that creates the most accurate statement based on the information provided.
Taken together, the 3 categories having the greatest frequencies account for % of the repairs in the sample.
Taken together, the 3 categories having the lowest frequencies account for % of the repairs in the sample.

1. We are given a graph and asked how much do the 3 categories with the lowest and greatest frequencies account for the repairs.
2. Note that the frequencies strictly decrease in the graph when going from left to right. This means the 3 categories we're looking for are either all to the leftmost side or rightmost side.
3. The 3 categories having the greatest frequencies. To find how much they account for, we need to take their sum or the cumulative frequency at point "exhaust". This will be around 70%.
4. The 3 categories having the lowest frequencies. To find how much they account for, we need to take their sum or the difference of cumulative frequencies at points "steering" and "fuel supply". This will be 100% - around 82% = 18%.
