Rani works at the laboratory.
As per the question, the rani went to the lab and there she worked on measuring the ear of the coworker she was measuring the circumference. She even matched the results with each coworker and made a scatter plot showing the trend line.
The answer is thus a slope of 0.48 mm as associated with age.
- As the slope of 0.48 is given and is rising or running. The s-line represents the average changes in the response of the (y) variable that's linked with a 1 unit of change in the (x) variable.
- The change in ear circumference is associated with a one-year increase in age.
- Thus for every 1-year increase in age, was 0.48 mm rise in-ear circumference.
