Construction of linear regression equation.

Wildlife scientists have measured the lengths of the heads and the lengths of complete bodies of several crocodiles of two different species. In a summary of the regression analysis given below, the dependent variable for each species is the length of the body.

 

Species I

Species II

R-squared

96.8%

97.3%

Intercept

-68.3793 cm

-21.2246 cm

Head length coefficient

7.40004

7.71626

Do the following.

Do the association between the sizes of the heads and bodies of the two species appear to be strong? Describe. Hint: Use the values of the correlation coefficient and its meaning in your explanation.
prepare the equation of the regression line for each of the species.
The crocodile skeleton found had a head length of 62 cm and a body length of 380 cm. Which species do you think it was? give details why.
