Table B is accurate

Step-by-step explanation:

Given

Observations: 21, 22, 20, 29, 25, 21, 21, 27, 26, 25

Required

An accurate frequency table

From both tables in the attachment; both tables use a grouped data to represent the grades.

The grouped data is as follows;

19-21

22-24

25 - 27

28-30

Breaking down these groups into bits:

19-21 :- 19, 20, 21

22-24 :- 22, 23, 24

25 - 27 :- 25, 26, 27

28-30:- 28, 29, 30

Looking up these values in the given data, we have

19-21 :- 21, 20, 21, 21

22-24 :- 22

25 - 27 :- 25, 27, 26, 25

28-30:- 29

Getting their frequencies

19-21 :- 4

22-24 :- 1

25 - 27 :- 4

28-30:- 1

Hence, the second table is accurate

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
