Expert Solution
Step 1: Write the given data and formulas

The given data is

1 2 10 5 3 3 2 20 1 1
6 3 13 2 2 1 26 3 1 3
1 2 1 7 1 2 3 1 2 12
1 4 2 2 29 1 1 1 8 5
1 4 2 1 1 1 1 6 1 2
3 3 6 1 3 1 1 5 1 18

We use the excel function "=QUARTILE.EXC(array, quart)" to find the quartiles. Note that the interquartile range is IQR=Q3-Q1 and Midhinge=Q1+Q32, where Q1 is the 1st quartile and Q3 is the 3rd quartile.
