Use this information to answer Question 26 to 29: Shown below is output for

regression analysis relating Y (dependent variable) and X (independent variable).

R2 = 99.5%

Variable Coefficient SE t-stat PValue

Intercept 123.141 1.382 89.1 <0.0001

Slope -5.57476 -0.1068 -52.2 <0.0001

26. (2 points) What is the estimated regression equation that relates Y to X?

27. (2 points) Is there a linear association between dependent and independent variable?

Test the hypothesis at = 0.05

28. What is the estimated value of Y if the value of X is 4.5?

29. State the value of coefficient of determination and interpret it.
