Answer 1

Answer:

pl give brainliest I spent my last braincells on this

Step-by-step explanation:

Mean- sum of observations/no of observations

= sum of observations/56+23+39+13+8

= $5*56 + 10*23 + 15*39 + 20* 13 + 25*8/ 56+23+39+13+8$

= 280+230+585+260+200/139

=1555/139  

=11.19

Median- arrange in ascending order-

8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,13,13,13,13,13,13,13,13,13,13,13,13,13,13,13,13,13,13,13,13,23,23,23,23,23,23,23,23,23,23,39,39,39,39,39,39,39,39,39,39,39,39,39,39,39,56,56,56,56,56.

find term= no of terms=5+10+15+20+25=75

since it is odd formula= $(75+1)/2$

=76/2 = 36th term

=13 is median

Mode- term repeated most times

= 8
