If the value of the Standard Error of the Estimate is 6.9, it means that Question 19 options: for each increase of 1 unit in X, the Y value is expected to increase by 6.9 units the Y variable is expected to have a value of 6.9 when the X value is 6.9 percent of the variability in Y is explained by the relationship with X about 68 percent of the predicted Y values will fall within 6.9 units on either side of the regression line
