Step-by-step explanation:
1)Given observations are 1.2,1.9,1.8,1.1
Sum of all observations=1.2+1.9+1.8+1.1=6
No. of observations=4
Mean=Sum of all observations/No. of all observations
=>6/4
=>3/2
=>1.5
Mean=1.5
-------------------------------------------------------------
2)Given observations are 14,18,19,22,28,33
writting them into ascending order
=>14,18,19,22,23,33
No. of observations=6 is an even number
If the number of observations 'n 'even then median is average of (n/2)th and (n/2)+1 th observations
=>average of 3,4 observations
=>(19+22)/2
=>41/2
=>20.5
Median=20.5
---------------------------------------------------------
3)Given observations are 0,9,9,8,8,12,12,13,7
Writting them into ascending order
=>0,7,8,8,9,9,12,12,13
Most occuring observations=8,9,12
Mode=8,9,12
-------------------------------------------------------------------
