Check Your Understanding
You may have heard that your nose and ears grow through your whole life. While it is true that your
nose and ears get bigger throughout life, it's not because they grow, but because of gravity. The
cartilage in your nose and ears break down as we age and the "growth" people observe is the result
of drooping. To quantify the expansion of ears over time, a random sample of 30 adults were
selected. For each adult, their age (in years) was recorded and their ear height (cm) was measured.
Below is the regression output. Is there convincing evidence of a positive linear relationship
between age and ear height? Assume the conditions for inference are met.
