2. Explain when we would use an independent t-test vs. a dependent t-test 3. What is the connection between the t-statistic, alpha, and degrees of freedom? (Hint, slide 45) 4. If the t-statistic is GREATER THAN the critical value, what happens to the null hypothesis? 5. If the t-statistic is LESS THAN the critical value, what happens to the null hypothesis? 6. When the null hypothesis is REJECTED, what does this mean for our statistical significance? 7. When we FAIL TO REJECT the null hypothesis, what does this mean for our statistical significance
