Question

please answer both pls...... it's very urgent..... please and all... ​

Answer 1

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

-------------------------------------------------------------------
