Answer 1

Step-by-step explanation:

Given observations are4.61;2.00;7.41;7.24;5.15;5.09;2.77;0.14;2.68

On writting them into ascending order

0.14 ; 2.00 ; 2.68; 2.77; 4.61; 5.08; 5.15; 7.41; 7.24

Sum of all observations=

0.14+2.00+2.68+2.77+4.61+ 5.08+5.15+7.41+7.24

=37.09

Number of all observations=9

Mean =Sum of all observations/No. of all observations

=>Mean=37.09/9

=>Mean=4.12 (approximately)

Median=(n+1)/2th observation

=>(9+1)/2=10/2=5 th observation

Median=4.61
