­chetan2u Isn't the range of scores for Day 4 and Day 5 same ?

­Yes, the range is the same for 4 and 5, But when you add one of these days to day 2, then the highest point between the two and the lowest point between the two will give you the range.

The graph shows the distributions of scores on official driving tests administered within a certain municipality for eight consecutive business days.

Select from each drop-down menu the option that creates the most accurate statement, given the information provided.

The graph provides enough information to determine that the [Dropdown Placeholder #1] over all of the days indicated in the graph is the same as that for [Dropdown Placeholder #2] combined.

­Solution:
Median: It is the middle value of all the scores placed in an order. But here we are dealing with only % of scores in a given range, so we cannot find Median.
Mean: The above is true for mean too.
Range: The highest score vs the lowest score. Here, we do get know the higest and lowest for each day. So, Range is the only measure of tendency that can be found.

From the above , we can say that we will have Range for blank 1.

Range for all days will be the highest - lowest values for all 10 days = Highest of Day 2 - lowest of day 5 = 90 - 20 = 70.
The above gives us the answer for blank 2. when we combine day 2 and day 5, the range here too will become 70 as shown above.
