Was there any evidence of baseline imbalance on systolic blood pressure at pretest? Report the estimated mean difference, t-value, p-value, and confidence interval. For results with more than two decimal places, report answers to the third decimal place.  mean difference = , t () = , p = , 95% C.I. = [, ]

Was there evidence of a baseline by treatment interaction effect of the intervention program on posttest? Report the regression coefficient, t-value, p-value, and confidence interval. For results with more than two decimal places, report answers to the third decimal place.  interaction = , t () = , p = , 95% C.I.  = [, ] 

Report the estimated eduyrssq coefficient, t-value, p-value, and confidence interval. For results with more than two decimal places, report answers to the third decimal place.  eduyrssq = , t () = , p = , 95% C.I. = [, ]

Was there an effect of the intervention on posttest systolic blood pressure holding baseline systolic blood pressure constant? 

Interpret the c’ path. Is the c’ path statistically significant? 

Which problem in prediction modeling is solved by the application of cross-validation? 

Report the regression coefficient for the c’ path, t-value, p-value, and confidence interval. For results with more than two decimal places, report answers to the third decimal place.  c’ path = , t () = , p = , 95% C.I. = [, ]

Referring to the figure below, the case marked with * indicates a case with high __________. 

For the linear relation between education years and total recall, interpret the intercept, slope, and 95% confidence interval for each.   Can you determine the statistical significance of the linear relation based only on the 95% confidence interval for education years?

Based on the sign the term eduyrssq, do you expect the shape to be concave up or concave down? Was this effect statistically significant?
