Answer 2

Answer:

ANSWER

In this table class intervals are such that Lower limit is included and upper limit is not included in the class.

That means In interval (30−35), 30 is included but 35 is excluded.

And for frequency we counted how many times number from the interval occurs in given data.

Class interval Frequency

25−30 = 2

30−35= 7

35−40 = 11

40−45 = 7

45−50 =3

Total =30

(I) The least frequency is 2 and is in the class 25−30

(ii) The maximum frequency is 11 and is in the class 35−40.
