The scatterplot shows Olympic gold medal performances in the long jump from 1900 to 1988. The long jump is measured in meters. The regression equation is predicted long jump = 7.24 + 0.014 * year since 1900.
The standard error, se, is about 0.2. In terms of estimating long jump distances, what does this value for the standard error mean?
a. On the average, estimates will be up to 0.2 meters too short.
b. On the average, estimates will be either be 0.2 meters too short or too long.
c. 20% of the error in the long jump estimates is explained by the year since 1900.
d. 4% of the error in the estimates is explained by the regression line.
