Question

The weights (in kg) of 30 students of a
class are :
39, 38, 36, 38, 40, 42, 43, 44, 33, 33, 31, 45,
46, 38, 37, 31, 30, 39, 41, 41, 46,36, 35, 34,
39, 43, 32, 34, 29, 26
Prepare a frequency distribution table using
tally mark with one of class interval as 30-
35 (35 not included)
and answer the following questions.
.
(ii) Which class interval has maximum frequeency​

Answer 1

$\huge \sf { \fcolorbox{green}{g}{✴ \: Explanation ✴}}$

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.

Answer 2

Answer:

pls mark brainliest answer

Step-by-step explanation:

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.
