The question asks who would appear in the upper-left corner of a scatter plot of Age vs. Height. In a scatter plot:

• The x-axis usually represents Age.
• The y-axis represents Height.
• The upper-left corner represents someone with a low age (x-value) and a high height (y-value).

From the table provided, let’s evaluate the people based on their age (lower is better for x-axis) and height (higher is better for y-axis):

1. John: Age 25, Height 175 cm
2. Emma: Age 30, Height 160 cm
3. Alex: Age 22, Height 180 cm
4. Sarah: Age 33, Height 165 cm
5. David: Age 28, Height 170 cm
6. Lily: Age 32, Height 158 cm
7. Mike: Age 27, Height 178 cm

Looking for someone with the smallest age and the largest height:

• Alex is the youngest (Age 22) and also has the highest height (180 cm).

Thus, the person appearing in the upper-left corner is Alex.

Answer: a. Alex

Would you like more details or have any other questions? Here are some additional related questions to deepen your understanding:

1. How do you interpret points in different quadrants of a scatter plot?
2. What could the slope of the trend line on a scatter plot of Age vs. Height tell you?
3. How would a scatter plot of Age vs. Weight differ from Age vs. Height?
4. Why might someone use a scatter plot instead of other chart types for this data?
5. What methods can be used to find correlations between Age and Height from the data?

Tip: The upper-left and lower-right corners in scatter plots are often key for identifying trends like negative correlations.
