1. The problem involves analyzing a scatter plot showing the relationship between the age of African grey parrots (x-axis) and the number of words they know (y-axis). 2. We want to understand the general trend and identify any outliers in the data. 3. From the scatter plot, most data points show a positive correlation: as age increases, the number of words known tends to increase. 4. The outlier is the point at approximately age 10 years with 70 words known, which is much higher than other parrots of similar age. 5. This suggests that while most parrots learn words gradually over time, some may learn significantly more words at a younger age. 6. To model this relationship, a linear function $y = mx + b$ could be used, where $y$ is words known and $x$ is age. 7. The slope $m$ represents the average increase in words known per year, and $b$ is the estimated number of words known at age 0. 8. Without exact data points, we cannot calculate $m$ and $b$ precisely, but the trend is positive. Final answer: The number of words known by African grey parrots generally increases with age, with some outliers learning many words early.
