It is suggested that eyelash length is proportional to the width of the eye. Consider the following scatter plot which displays eyelash length and eye width for several different mammals. Eye Lashes and Eye Width 1.3 16 14 12 21 Eye Lash Lenght (cm) 08 06 A 02 05 1 15 35 4 45 Eye Width (cm) Eye Lash Length 0.3109 Eye Width + 0.053 gives the Least Squares Regression Line and the correlation coefficient is calculated to be r-0.844. Fill in the following information, rounded to 3 decimals if applicable. You should not include units. 1. The average human eye is 2.37 cm wide. How long do you expect the average human eye lashes to be? 2. An elephant has the longest eyelashes of any mammal averaging at 12.7 cm long. Assuming that the trend holds, how wide do you expect the average elephant eye to be? percent of all variation in mammal eye lash length is explained by the least-squares regression line. So of all variation in mammal eye lash length is due to the scatter of the points. percent It is suggested that eyelash length is proportional to the width of the eye.
