Answer:
a. A dog's tail will wag differently in response to positive stimuli and to negative stimuli.
Step-by-step explanation:
A research hypothesis is a proposition that can be tested about the possible outcome of a study based on different stimuli.
A research hypothesis is a specific, clear, and testable proposition or predictive statement about the possible outcome of a scientific research study based on a particular property of a population, such as presumed differences between groups on a particular variable or relationships between variables.
Before a quantitative study takes place, it is important to state the research hypothesis because it is very important to the study.
There is usually an expectation or predicted outcome of the study because the research is determined by the hypothesis.
So it was already hypothesised that a dog would wag its tail in a preferred direction when it is faced with negative or positive stimuli. So the hypothesis was tested as different sets of dogs were placed in a cage and introduced to different stimuli.
From the observation of the researchers, all the dogs wagged their tails to the right when they saw a familiar face (positive stimuli) and wagged their tails to the left when they faced an aggressive dog (negative stimuli)
