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
From the complete question, the samples in the third row are:
Sample: 3 4 3 0 1
The mean of a dataset is calculated using:
Where:
n = 5 i.e. the number of samples
So, we have:
Add the expressions in the numerator
Divide 11 by 5
Hence, the mean of the sample in the third row is 2.2
