Question

Following table shows a frequency distribution for the speed of cars passing through particular spot on a national highway :
$\begin{matrix} C l a s s I n t e r v a l s (k m / h) : & 40 - 50 & 50 - 60 & 60 - 70 & 70 - 80 & 80 - 90 & 90 - 100 & 100 - 110 F r e q u e n c y : & 5 & 8 & 30 & 70 & 55 & 33 & 12 \end{matrix}$
Draw a histogram and frequency polygon representing the data above.

Solution

Note : - Both the areas are not calibrated
Since : - Class interval started will 40 - 50 so in this case, we used zig - zag line
