Give one example of a situation in which $(i)$ the mean is an appropriate measure of central tendency.

The following table gives the distribution of students of two sections according to the marks obtained by them:

Marks (Section $A$)	Frequency (Section $A$)	Marks (Section $B$)	Frequency (Section $B$)
$0-10$	$3$	$0-10$	$5$
$10-20$	$9$	$10-20$	$19$
$20-30$	$17$	$20-30$	$15$
$30-40$	$12$	$30-40$	$10$
$40-50$	$9$	$40-50$	$1$

Represent the marks of the students of both the sections on the same graph by two frequency polygons. From the two polygons,compare the performance of the two sections.

Van Mahotsava was celebrated in $100$ schools,where $100$ plants were planted in each school. After one month,the number of plants that survived were recorded as follows:
$\begin{array}{llllllllll}95 & 67 & 28 & 32 & 65 & 65 & 69 & 33 & 98 & 96 \\ 76 & 42 & 32 & 38 & 42 & 40 & 40 & 69 & 95 & 92 \\ 75 & 83 & 76 & 83 & 85 & 62 & 37 & 65 & 63 & 42 \\ 89 & 65 & 73 & 81 & 49 & 52 & 64 & 76 & 83 & 92 \\ 93 & 68 & 52 & 79 & 81 & 83 & 59 & 82 & 75 & 82 \\ 86 & 90 & 44 & 62 & 31 & 36 & 38 & 42 & 39 & 83 \\ 87 & 56 & 58 & 23 & 35 & 76 & 83 & 85 & 30 & 68 \\ 69 & 83 & 86 & 43 & 45 & 39 & 83 & 75 & 66 & 83 \\ 92 & 75 & 89 & 66 & 91 & 27 & 88 & 89 & 93 & 42 \\ 53 & 69 & 90 & 55 & 66 & 49 & 52 & 83 & 34 & 36\end{array}$

The following number of goals were scored by a team in a series of $10$ matches:
$2, 3, 4, 5, 0, 1, 3, 3, 4, 3$
Find the mean,median,and mode of these scores.

$A$ random survey of the number of children of various age groups playing in a park was found as follows:

Age (in years)	Number of children
$1-2$	$5$
$2-3$	$3$
$3-5$	$6$
$5-7$	$12$
$7-10$	$9$
$10-15$	$10$
$15-17$	$4$

Draw a histogram to represent the data above.

Given below are the seats won by different political parties in the polling outcome of a state assembly elections:

Political Party	$A$	$B$	$C$	$D$	$E$	$F$
Seats Won	$75$	$55$	$37$	$29$	$10$	$37$

$(i)$ Draw a bar graph to represent the polling results.
$(ii)$ Which political party won the maximum number of seats?
