Rani went around the laboratory where she works and measured her
coworkers' ear. circumference (in millimeters). Then she matched her results with each coworkers' age and created the following scatter plot and trend line. Assuming the line correctly models the trend in the data, what does this line's slope of 0.480 mean?

Select one:

A)On average, each 1 year increase in age was associated with a 0.48 millimeter
increase in ear circumference.

B)On average, each 1 millimeter increase in ear circumference was associated with
a 0.48 year increase in age.

C)The average age was 48 years old.

D)The average ear circumference was 0.48 millimeters
