pls answer fast

Prepare a frequency distribution table by taking class interval of width 5 and draw the
histogram for the given data:
The weight ( in kg) of 30 students of a class are:
39, 38, 36, 38, 40, 42, 43, 44, 33, 31, 45, 46, 38, 37, 31, 30, 30, 39, 41, 41,
46, 36, 35, 34, 39, 43, 32, 37, 29, 26.

Answer 1

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
