It is urgent so please answer fast and it is an earnest request that if you do not know the answer don't answer it just with the purpose of gaining points by writing" I don't know"​

Answer 1

Answer:

This is inconsistent so just add or subtract 0.5

Step-by-step explanation:

the upper classes are : 19.5 , 29.5 , 39. 5 and 49.5 resp.

the lower classes are : 9.5, 19.5 , 29.5, 39.5 resp.

Mid values - 14.5, 24.5 , 34.5 , 44.5 resp.

P.S ( the question has an error. The last class should be 40-49)

Have fun!

Answer 2

Answer:

lower class limit for:

10-19 = 10

20-29 = 20

30-39 = 30

42-49 = 42

upper class limit for:

10-19 = 19

20-29 = 29

30-39 = 39

42-49 = 49

mid values for:

10-19 = 10+19/2 = 14.5

20-29 = 20+29/2 = 24.5

30-39 = 30+39/2 = 34.5

42-49 = 42+49/2 = 45.5

hope this helps!
