Approximately what percentage of the people aged 25-40 had a systolic blood pressure reading between 110 and 139 inclusive? Relative Frequency 0.35 0.30 0.25 0.20 0.15 0.10 005 0,00 100 110 120 130 140 150 160 Systolic Blood Pressure (mm Hg 8) Construct a histogram using the frequency distribution created in exercise 6.

Bar Graphs

A bar graph is a chart or graphical representation of data. A bar chart, also known as a bar graph, is a graph or chart that displays categorical data using rectangular bars with heights or lengths equal to the values they represent. Typically, bar graphs show categorical and numerical variables grouped in class intervals. A bar graph is useful for comparing and analyzing a set of data.
