Final Answer:
The cumulative frequency and cumulative relative frequency polygons illustrate a gradual increase in selling prices of houses in the Billings, Montana area, showcasing a more detailed perspective of the distribution and its proportions.
Step-by-step explanation:
The cumulative frequency polygon displays the total frequency of houses sold up to each price point, revealing a steady rise in the number of houses sold as prices increase. Similarly, the cumulative relative frequency polygon demonstrates the proportion of houses sold at or below specific price levels, highlighting the distribution's cumulative nature.
Notable observations might include an upward trend indicating a larger concentration of houses sold at higher prices, potentially suggesting a trend of higher-priced properties dominating the market or a preference for certain price ranges among buyers. An analysis of these trends aids in understanding the market dynamics and preferences within the Billings housing market.
