Answer 2

Hi friend,

* first draw a table which has three rows and write class intervals and frequency and mention the given values and find midvalues for class intervals. ex:150+200-2=175

* take a graph.draw x axis and y axis mention class intervals on y axis and even numbers (2,4,6,8,10.....)on x axis.

mark the frequency on graph as histogram and write the scale on top right.

take suceeding class interval of last class interval and also preceeding class interval of first class interval.

mark the midpoint of every class interval in histogram and joins them. take midpoint at zero at first class interval (preceeding of 150-200)and join them and last one(succeeding of 450-500)zero point and join them.

hope it helps.
