To find the mean of the sample in the third row, follow these steps:

1. Identify the numbers in the third row. The third row of the table is:
[tex]\[3, 4, 3, 0, 1\][/tex]

2. Add all the numbers in the third row together:
[tex]\[ 3 + 4 + 3 + 0 + 1 = 11 \][/tex]

3. Count the number of values in the third row. There are 5 values.

4. Divide the sum of the numbers by the number of values to find the mean:
[tex]\[ \frac{11}{5} = 2.2 \][/tex]

Thus, the mean of the sample in the third row is:
[tex]\[2.2\][/tex]

So, the correct answer is:
[tex]\[2.2\][/tex]
