Question

Looking at the means of these samples, which value is most likely to be the mean of the population from which the samples were taken? Sample Number Sample Mean 1 11.8 2 12.5 3 15.1 4 14.3 5 13.0 6 12.9 10.2 11.5 12.9 15.4

Answer 1

Answer:

We are given the below data:

Sample Number              Sample Mean

1                                                 11.8

2                                                 12.5

3                                                 15.1

4                                                 14.3

5                                                 13.0  

6                                                 12.9

7                                                 10.2  

8                                                 11.5

9                                                 12.9

10                                                15.4

Now the most likely mean of the population can be found by finding the mean of given sample means. It is given below:

$Mean = \frac{11.8+12.5+15.1+14.3+13.0+12.9+10.2+11.5+12.9+15.4}{10}$

               $=12.96$

Therefore, the most likely mean of the population from which the samples were taken is 12.96
