29 30 32 34 37 41 40 31 33 35 38 40 32 37 37 39 38 37 37 36
Arrange the given data in a tubular form using tally mark ​

Answer 1

Answer:

Step-by-step explanation:

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
