Explanation:

Step1: Analyze the data range

The daily high temperatures (x - axis) range from 50 to 85, and pollen counts (y - axis) range from 22 to 506.

Step2: Check the y - axis scale of the scatter plots

The left scatter plot has a y - axis scale (pollen count) that goes up to 500+, which matches the pollen count range (22 - 506). The right scatter plot has a y - axis scale up to 110, which is too small for the pollen counts (e.g., 435, 506 are much larger than 110).

Step3: Check the x - axis scale

The left scatter plot's x - axis (temperature) ranges up to 80+, which matches the temperature range (50 - 85). The right scatter plot's x - axis is mislabeled (it has temperature on x - axis but the scale is 0 - 500, which is incorrect for temperature). Also, the data points in the left plot should align with the temperature - pollen count pairs. For example, when temperature is 50, pollen count is 28; when temperature is 85, pollen count is 506. The left plot's points at lower x (around 50 - 60) have lower y (around 22 - 125) and at higher x (70 - 85) have higher y (187 - 506), which matches the data. The right plot's y - axis is too small and x - axis is misrepresented.

Answer:

The left scatter plot (the first one labeled "Temperature and Tree Pollen Count" with y - axis up to 500 and x - axis up to 80)
