The statement "A prediction based on the data is reliable because the means of the samples are close together." is correct.

What is mean?

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

We have data:

Sample 1 14 15 16 17 16 15 16 15 17 18

Mean for sample 1 = 15.9

Sample 2 16 18 17 14 15 14 18 14 15 16

Mean for sample 2 = 15.7

Sample 3 18 14 16 15 15 14 17 15 19 13

Mean for sample 3= 15.6

As we can see, the mean of the data sample 1, 2, and 3 are very close.

So the prediction based on the data is reliable.

Thus, the statement "A prediction based on the data is reliable because the means of the samples are close together." is correct.
