Answer 1

Answer:

Input Data :

Data set = 5, 8, 12, 15, 20

Total number of elements = 5

Objective :

Find what is harmonic mean value for given input data?

Formula :

Harmonic Mean Formula

Solution :

Harmonic mean =

5

1/5 + 1/ 8 + 1/ 12 + 1/ 15 + 1/ 20

=

5

0.2 + 0.125 + 0.0833 + 0.0667 + 0.05

=

5

0.525

Harmonic mean = 9.5238
