**Dependent t-test**
Use the following data and scenario to answer the questions. A dog trainer is interested in whether the type of environment (park or training facility) will influence how quickly dogs learn a new skill. The dog trainer obtained 40 dogs to participate in the training program. First the 40 dogs learned a new skill at the park and the dog trainer recorded how many hours it took for each dog to learn the new skill. Then the 40 dogs learned a new skill at the training facility and the dog trainer recorded how many hours it took for each dog to learn the new skill. Can we conclude that the type of environment significantly influences how quickly dogs learn a new skill?
Alternative Hypothesis: The type of environment significantly influences how quickly dogs learn a new skill.
Null Hypothesis: The type of environment will not significantly influence how quickly dogs learn a new skill.
Use the following data to answer the following questions:
1. Is the study significant?
2. Is p <.05 or p>.05?
3. Do you reject or retain the null hypothesis?
4. What can you conclude about the hypothesis for this study?
5. What is the statistical sentence?
6. What is the independent variable?
7. What are the independent variable levels?
8. What is the dependent variable?
