$A$ 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.

$A$ survey conducted by an organisation for the cause of illness and death among women between the ages $15-44$ (in years) worldwide,found the following figures (in $\%$):

$S$.No	Causes	Female fatality rate $(\%)$
$1.$	Reproductive health conditions	$31.8$
$2.$	Neuropsychiatric conditions	$25.4$
$3.$	Injuries	$12.4$
$4.$	Cardiovascular conditions	$4.3$
$5.$	Respiratory conditions	$4.1$
$6.$	Other causes	$22.0$

$(i)$ Represent the information given above graphically.
$(ii)$ Which condition is the major cause of women's ill health and death worldwide?
$(iii)$ Try to find out,with the help of your teacher,any two factors which play a major role in the cause in $(ii)$ above being the major cause.

The heights of $50$ students,measured to the nearest centimetres,have been found to be as follows:
$\begin{array}{llllllllll}161 & 150 & 154 & 165 & 168 & 161 & 154 & 162 & 150 & 151 \\ 162 & 164 & 171 & 165 & 158 & 154 & 156 & 172 & 160 & 170 \\ 153 & 159 & 161 & 170 & 162 & 165 & 166 & 168 & 165 & 164 \\ 154 & 152 & 153 & 156 & 158 & 162 & 160 & 161 & 173 & 166 \\ 161 & 159 & 162 & 167 & 168 & 159 & 158 & 153 & 154 & 159\end{array}$
$(i)$ Represent the data given above by a grouped frequency distribution table,taking the class intervals as $150-155, 155-160,$ etc.
$(ii)$ What can you conclude about their heights from the table?

The following table gives the life times of $400$ neon lamps:

The time (in hours)	Number of lamps
$300-400$	$14$
$400-500$	$56$
$500-600$	$60$
$600-700$	$86$
$700-800$	$74$
$800-900$	$62$
$900-1000$	$48$

$(i)$ Represent the given information with the help of a histogram.
$(ii)$ How many lamps have a life time of more than $700$ hours?

The runs scored by two teams $A$ and $B$ on the first $60$ balls in a cricket match are given below:

Number of balls	Teams $A$	Teams $B$
$1-6$	$2$	$5$
$7-12$	$1$	$6$
$13-18$	$8$	$2$
$19-24$	$9$	$10$
$25-30$	$4$	$5$
$31-36$	$5$	$6$
$37-42$	$6$	$3$
$43-48$	$10$	$4$
$49-54$	$6$	$8$
$55-60$	$2$	$10$

Represent the data of both the teams on the same graph by frequency polygons.
[Hint : First make the class intervals continuous.]
