# Statistics - Hypothesis Testing

1. How can we tell the direction (left tail, two-tailed, and right tailed test) of a hypothesis test?

2. When would we choose a two tailed test by looking at a pair of hypothesis?

3. How can we tell which direction (or no direction) to make the hypothesis by looking at the problem statement (research question)?

4. How is the null hypothesis chosen (why is it null)?

5. What is the importance of rejecting the null hypothesis in relation of the sample to the population?

6. With a failure to reject the null hypothesis, can we make a general statement about the population based on the sample findings?
