The mean of a dataset is the average of the dataset.

The mean of the sample in the third row is 2.2

The dataset is given as:

5 5 3 0 6 2 2 4 5 2 3 4 3 0 1 4 0 4 3 6

Sample: 3 4 3 0 1

The mean of a dataset is calculated using:

\bar x = \frac{\sum x}{n}

Where:

n = 5 i.e. the number of samples

So, we have:

\bar x = \frac{3 + 4 + 3 + 0 + 1}{5}

Add the expressions in the numerator

\bar x = \frac{11}{5}

Divide 11 by 5

\bar x = 2.2

Hence, the mean of the sample in the third row is 2.2
