Histograms

[crazymoo]

Hi the complete info i have is as follows:

Q. The table gives information about how long in minutes,
students took to complete a puzzle.

The Table:
Time (t) in minutes Frequency
0 < t (> with - under it) 1020
10< t (> with - under it) 1530
15 <t (> with - under it) 3060
30 < t (> with - under it) 6090

Use the table to draw a histogram.


The graph to place it on has nothing on the vertical, on horizontal 0 - 60 (in tens) underneath Time (t) in minutes.

Hope this is clear enough as i do not understand it at all to be able to describe it any better.

Thank you if you can help.
