Suppose the points (10, 0), (20, 4), (30, 12), (40, 18), (50, 9), (60, 7), (70, 0) were connected to form a frequency
polygon. Use this information to answer the following questions:
- What was the bin size of the histogram on which the frequency polygon is based?
- Which bin had the highest frequency?
- Which bin had the lowest frequency?
- What percentage of the data had a value below 55?
Use the histogram shown below to answer the following questions:
- How many points would be connected to form the corresponding frequency polygon? (Include the points
added to give the frequency polygon the appearance of having a starting point and an ending point.) - List the points.
- Create the frequency polygon.
