1. Find Arithematic mean for data `5,4,6,3,7,5`
Solution:
AM `=(x_1+x_2+x_3+x_4+x_5+x_6)/6`
`=(5+4+6+3+7+5)/6`
`=30/6`
`=5`
2. Find Geometric mean for data `5,4,6,3,7,5`
Solution:
GM `=root (6)(x_1 xx x_2 xx x_3 xx x_4 xx x_5 xx x_6)`
`=root (6)(5 xx 4 xx 6 xx 3 xx 7 xx 5)`
`=root (6)(12600)`
`=4.8239`
3. Find Harmonic mean for data `5,4,6,3,7,5`
Solution:
HM `=N/(1/x_1+1/x_2+1/x_3+1/x_4+1/x_5+1/x_6)`
`=6/(1/5+1/4+1/6+1/3+1/7+1/5)`
After solving, we get
HM `=4.6409`
