What is a testable hypothesis for an experiment that compares wild horses and tame horses?

Testable Hypothesis:

Wild horses will exhibit a greater startle response to sudden, unexpected noises compared to tame horses.

Explanation:

* Independent Variable: The type of horse (wild vs. tame)

* Dependent Variable: The intensity of the startle response (measured by heart rate, behavioral changes, or other quantifiable indicators)

* Control Group: Tame horses

* Experimental Group: Wild horses

* Control Variables: Age, breed, gender, and similar environmental factors should be controlled to minimize confounding variables.

Experiment Design:

1. Sample Selection: Choose a group of wild horses and a group of tame horses, matching them for age, breed, and gender.

2. Baseline Measurement: Record the baseline heart rate and other relevant physiological measures for all horses in a calm environment.

3. Stimulus: Introduce a sudden, unexpected noise (like a loud clap or bang) to all horses.

4. Measurement: Immediately after the noise, record the heart rate and observe behavioral changes (e.g., jumping, running, freezing) in both groups.

5. Data Analysis: Compare the startle response data (heart rate, behavioral changes) between the two groups.

Expected Outcome:

Based on the hypothesis, wild horses are expected to have a significantly higher heart rate and more pronounced behavioral changes compared to tame horses in response to the sudden noise. This suggests that wild horses, due to their history of living in unpredictable environments, are more sensitive to sudden stimuli.

Note: This is just one example. You can formulate different testable hypotheses based on other observable differences between wild and tame horses.
