(10 points) O a. One-sided T-test Ob. Two-sided T-test O c. Regression Od. Confidence interval Il) Statistical interpretation? (5 points) O a. Since P-value is small we are confident that the slope is not zero. Ob. Since P-value is small we are confident that one average is smaller than the other. Oc. Since P-value is too large the test is inconclusive. Od. None of these. Ill) Conclusion? (5 points) O a. Yes, we can confirm the assertion. Ob. No, we cannot confirm the assertion
