Question

The table lists chest sizes (distance around chest in inches) and weights (in pounds) of anesthetizedbears that were measured. Find the value of the linear correlation coefficient r using your Ti 83/84calculator. Round your answer to 3 decimal places.Chest (in) Weight (lb)26894530454400149348351674122341289

Answer 1

The value of the linear correlation coefficient r is 0.981

Here, we want to calculate the value of the linear correlation coefficient

We have the plot of the linear regression as given below;

So, from here, we proceed to get r from the plot

Looking at the data obtainable, we can see that the value of r from the graphing calculator is 0.9811

Writing this to 3 decimal places, we have 0.981
