Answer 2

Explanation:

Given:-

given observations are 1/2;2/3;1/4;3/5

To find:-

Average of 1/2;2/3;1/4;3/5

Solution:-

Given observations are 1/2;2/3;1/4;3/5

No. of observations =4

Sum of observations= 1/2+2/3+1/4+3/5

LCM of 2,3,4,5 is 60

=>(30+40+15+36)/60

=>121/60

Average = Sum of all observations/No. of observations

=>Average=(121/60)/4

=>121/(60×4)

=>121/240

Answer:-

Average of the given observations=121/240
