Question 2. A researcher was interested in investigating a relationship between the age (independent variable) of a driver and the distance the driver can see. For this purpose, he collected data on 30 drives. The data with some purposefully missing/omitted information is provided in Appendix \"1 \". To help you with your analysis, partial summary statistics are provided below: SSxx = 13,752 SSxy = - 41,350 SSyy =l93,667 Z x = 2 Age = 1,530; E y = (Distance the driver can see)=12,700 a) Write the estimated regression line (4pts) b) Is the relationship meaningful (signicant at a=0.05)? (3 pts) make sure to state the null and alternative hypothesis rst. c) What is the strength of the relationship? It is signicant? (2 pts) d) What is the coefcient of determination? (2 pts) e) What is the Adjusted R-sq? (2 pts) f) John is 61 years old. What is the expected driving distance for him? What is the 95% prediction interval for John? (2 pts)
