I have to answer this with 60 minutes. Please help.The numbers below are grouped into 5 numbers. The last 3 lines are grouped by four numbers

The following data represent the concentration of organic carbon collected from mineral soil.

(Data is already organized in ascending order ... smallest to largest)

3.02 7 8.5 10.74 16.92

3.79 7.11 8.5 10.89 17.9

3.91 7.31 8.79 11.33 17.99

3.99 7.45 9.1 11.56 21

4.6 7.66 9.11 11.72 21.4

4.71 7.85 9.29 11.72 21.82

4.8 7.9 9.6 11.8 22.62

4.85 7.92 9.81 11.97

4.9 8.05 10.3 12.57

5.5 8.37 10.72 12.89

1. Compute the quartiles. Q1 is, Q2 is, and Q3 is
2. Quartiles are data values that separate your data set into _________equal parts.
