WebWork 3 Measures of Data

For WebWork 3 I was presented with a Box & Whisker plot shown below.The directions asked me to find the five-number summary. I understand that the minimum is 5 and that the maximum is 13. I also understand that the median is marked by the vertical line inside of the box above the number 7. However, I am confused about how to find the first and third quartile using R. When I make a list and tell the computer to give me a summary for the box plot it does not come up with the right answers. Any advice would be spectacular!

@ejoy90 This is not actually a question involving R; you should be able to do it completely from the figure.

@mark Cool! That is what I eventually did since I couldn't get it to work in R.
