Answer 1

Given :   The weight of 25 students of standard 8 is shown in kilograms.

.33 46 55 52 43 39 38 53 43 45 37 49 42 46 43 38 43 47 42 48 39 40 48 51 50​

To Find : a frequency distribution table of students  in which one group is of 46-50

Solution:

CLASS       Tally Marks  Frequency

31 - 35         |                 1

36 - 40       $\setlength{\unitlength}{0.5cm} \begin{picture}(4,4) \multiput(2, 1)(0.2, 0){4}{\line(0, 1){0.5}} \put(1.8, 1){\line(2, 1){1}} \end{picture}$ |           6

41 - 45        $\setlength{\unitlength}{0.5cm} \begin{picture}(4,4) \multiput(2, 1)(0.2, 0){4}{\line(0, 1){0.5}} \put(1.8, 1){\line(2, 1){1}} \end{picture}$ ||           7

46 - 50       $\setlength{\unitlength}{0.5cm} \begin{picture}(4,4) \multiput(2, 1)(0.2, 0){4}{\line(0, 1){0.5}} \put(1.8, 1){\line(2, 1){1}} \end{picture}$ ||           7

51 - 55         ||||               4

Answer 2

Step-by-step explanation:

CLASS Tally Marks Frequency

31 - 35 | 1

36 - 40 \setlength{\unitlength}{0.5cm} \begin{picture}(4,4) \multiput(2, 1)(0.2, 0){4}{\line(0, 1){0.5}} \put(1.8, 1){\line(2, 1){1}} \end{picture} | 6

41 - 45 \setlength{\unitlength}{0.5cm} \begin{picture}(4,4) \multiput(2, 1)(0.2, 0){4}{\line(0, 1){0.5}} \put(1.8, 1){\line(2, 1){1}} \end{picture} || 7

46 - 50 \setlength{\unitlength}{0.5cm} \begin{picture}(4,4) \multiput(2, 1)(0.2, 0){4}{\line(0, 1){0.5}} \put(1.8, 1){\line(2, 1){1}} \end{picture} || 7
