Wednesday 03 February 2010 I ran from Dolihner up towards Pit Stop, circled around past PICS, down to Kaselehlie and Elenieng, out to the U border, back into town through the public market, up to Spanish wall, up main street and back into Dolihner. Using a global positioning satellite receiver (GPS) and a chronometer I determined both my distance in kilometers and my time in minutes. In the world of running, a key metric is one's pace. Pace is the number of minutes per kilometer. Remember that *best fit line*, *least squares*, *linear regression*, and *linear trend line* all mean the same thing.

- ______________ Determine the slope of the linear trend line for the data.
- ______________ Determine the y-intercept of the linear trend line for the data.
- ______________ As I reached my turn-around at the bridge on the border between U and Nett my GPS said I was 7.45 kilometers into my run. I did not check my chronometer. Use the slope and intercept determined above to calculate the time in minutes at which I reached the U border.
- ______________ At an hour I usually try to rehydrate by picking up a bottle of water or a packet of juice. Using the above slope and intercept, determine my distance in kilometers at the one hour mark.
- ______________ Calculate how long for me to run the 80 kilometers around the circumferential road of Pohnpei.
- ______________ Based on the appearance of the xy scatter graph, does the relation appear to be
**strong**,**weak**,*OR***none**?
