Here's what I get  

Step-by-step explanation:

Assume your frequency table is like that in the table:

[tex]\begin{array}{cc}\textbf{Age Range} & \textbf{Frequency}\\20 \leq x < 30& 160\\30 \leq x < 40& 130\\40 \leq x< 50& 100\\50 \leq x < 60& 115\\60 \leq x < 70& 125\\70 \leq x < 80& 135\\\end{array}[/tex]

In a histogram, the data are grouped into ranges and then plotted as vertical bars. The height of each bar shows how items are in each range.

Your histogram should resemble the one below.
