12, 14, 15, 23, 22, 26, 28, 19, 17, 18, 25, 28, 29, 19, 12, 19, 22, 19, 23, 24, 19, 25, 19

Mean =

Median =

Mode =

Range =

Standard Deviation =

Answer 1

Here we have data:

12, 14, 15, 23, 22, 26, 28, 19, 17, 18, 25, 28, 29, 19, 12, 19, 22, 19, 23, 24, 19, 25, 19

Mean:

= 20.7391

Median:

Mode:

Range:

Note: Here not clear that data is taken from sample or population so i find out both sample standard deviation and population standard deviation, please select accordingly.

Sample standard deviation:

= 24.2016

Population standard deviation:

= 4.8114
