What does a hypothesis primarily describe in an A/B testing activity?
The correct answer is A. The expected outcome based on assumptions. In A/B testing, a hypothesis is a statement that predicts what you expect to happen and why - for example, "Changing the button color to red will increase click-through rate by 10% because it draws more attention." It articulates an assumption about cause and effect before the…

Explanation
In A/B testing, a hypothesis is a statement that predicts what you expect to happen and why - for example, "Changing the button color to red will increase click-through rate by 10% because it draws more attention." It articulates an assumption about cause and effect before the test runs, which is why A is correct. Options B, C, and D describe parameters you configure when designing the test (sample size, significance threshold, and test duration), not the hypothesis itself - they answer "how do we run the test?" rather than "what do we believe will happen?" A helpful memory tip: think of a hypothesis as the "If → Then" statement you write before touching any test settings - everything else (users, significance, duration) flows from it.
