-A high school student wonders if there is a correlation between the average life span of an animal and the
number of letters in its name. She gathers the following data:
Animal Average Life Span (years)
Goat 15
Chicken 15
Fox 14
Hare 10
Galapagos Land Tortoise 193
She obtains a high correlation coefficient of 0.98 and concludes that using a linear model, the number of letters in an
animal’s name can be used to predict its average life span.
