📉 Scuba Diver Depth vs. Water Temperature Graph
The image is a scatter plot titled "Scuba Diver Depth vs. Water Temperature." This graph illustrates the relationship between the depth of a scuba diver and the corresponding water temperature.

X-Axis (Horizontal): Labeled "Depth of a Scuba Diver (Ft)", representing the depth in feet, ranging from 0 to 120 feet.

Y-Axis (Vertical): Labeled "Water Temperature (
∘
F)", representing the temperature in degrees Fahrenheit, ranging from 0 to 120
∘
F.

Key Observations:
Data Trend: The data points show a strong negative correlation. This means as the scuba diver's depth increases (moving right on the x-axis), the water temperature consistently decreases (moving down on the y-axis).

Specific Points:

Near the surface (shallow depth, close to 0 Ft), the temperature is high, around 100
∘
F.

At the deepest point shown (around 100 Ft), the temperature is very low, around 10
∘
F.

In summary, the graph clearly demonstrates that water temperature decreases significantly as the depth increases.Looking at the graph, which statements are true? Check all that apply.

It is a probabilistic interpretation to say that the water temperature drops as the scuba diver goes deeper into the water.

The temperature seems to be dropping 1 degree per foot as the diver dives deeper.

We can use a deterministic interpretation to say that the water temperature would be over 120 degrees if the scuba diver was -10 ft out of the water.

The water would hit zero degrees after diving down about 125 feet.

The water temperature is usually about 110 degrees on the surface of the water.

Answer 1

True:
- It is a probabilistic interpretation to say that the water temperature drops as the scuba diver goes deeper into the water. (This is a probabilistic/summary statement about the trend in the scatter — temperature generally decreases with depth, but individual points vary.)
- (same statement repeated) — also true.

False:
- The temperature seems to be dropping 1 degree per foot as the diver dives deeper. (The drop is about 90°F over 100 ft ≈ 0.9°F/ft, not exactly 1°F/ft.)
- We can use a deterministic interpretation to say that the water temperature would be over 120 degrees if the scuba diver was -10 ft out of the water. (Deterministic extrapolation is not appropriate; the plotted surface temperature is ≈100°F.)
- The water would hit zero degrees after diving down about 125 feet. (Linear extrapolation from the plot gives zero around ≈111 ft, not 125 ft.)
- The water temperature is usually about 110 degrees on the surface of the water. (The plot shows surface temperature ≈100°F, not 110°F.)
