When bears were anesthetized, researchers measured the distance (in inches) around their chests and they weighed the bears (in pounds). Based on the results, does a bear's weight seem to be related to its chest size? Do the results change if the chest measurements are converted to feet? (You need to determine r)

X Chest (in.), Y Weight (lb.) (X,Y) 26,90; 45,344; 54,416; 49,348; 41,262; 49,360; 44,332; 19,34

Is there a linear correlation? How strong? Positive or negative correlated? Predict the weight of a bear whose chest measures 30 in.?
 
I think these are right

The weight does seem to be related to chest size

I don't know how to figure out the in to feet though I pluged it into my claculator but I still can't figure it out

Yes there is a liinear corielation.
Very strong r=.993
Positive r=.993
At a 30 in chest the weight would be approx. 150.64
 
Why do you care about feet? All normal bears have four.

# of feet = (# of inches)/12

The results are identical. Changing units does nothing. Do it in miles if you like. If you can handle the precision, you can do it in parsecs and get the same result.

I get r = +0.9927 and 30" bear might be around 150.67 lbs.

Seems to me that you have a clue! Good work.
