We feel that the cost depends on the destination and how busy it is or how much demand there is to get there. ksmith1010 https://padlet.com/ksmith1010/jf0x8orudyb9/wish/164743568 2017-04-04 21:19:42 UTC https://padlet.com/ksmith1010/jf0x8orudyb9/wish/164743568 4. When X is increased, one would think that logically the y axis would increase as well. However, in the data we found, while x increasing would usually cause y to increase, in some instances y would decrease when x would increase. This is probably because some of the places that were further away had less of a demand. ksmith1010 https://padlet.com/ksmith1010/jf0x8orudyb9/wish/164743907 2017-04-04 21:21:52 UTC https://padlet.com/ksmith1010/jf0x8orudyb9/wish/164743907 ksmith1010 https://padlet.com/ksmith1010/jf0x8orudyb9/wish/164744616 2017-04-04 21:27:17 UTC https://padlet.com/ksmith1010/jf0x8orudyb9/wish/164744616 5. If 2 cities are about 200 miles apart, then based on your regression line equation, by how much should their airfares differ? ksmith1010 https://padlet.com/ksmith1010/jf0x8orudyb9/wish/164744687 428.76-421.64= 7.12 If you were to add 200 miles to our trip it would add 7.12 according to our chart]]> 2017-04-04 21:27:48 UTC https://padlet.com/ksmith1010/jf0x8orudyb9/wish/164744687 6. Use Excel to produce r. How well does the line fit the data? ksmith1010 https://padlet.com/ksmith1010/jf0x8orudyb9/wish/164744809  R= .3622 It does fit the data.  The data shows a slight increase, as does the line]]> 2017-04-04 21:28:50 UTC https://padlet.com/ksmith1010/jf0x8orudyb9/wish/164744809 Prediction of the cost of flying 600 miles: $474.04 ksmith1010 https://padlet.com/ksmith1010/jf0x8orudyb9/wish/164744878 2017-04-04 21:29:28 UTC https://padlet.com/ksmith1010/jf0x8orudyb9/wish/164744878 ksmith1010 https://padlet.com/ksmith1010/jf0x8orudyb9/wish/164745019 2017-04-04 21:30:48 UTC https://padlet.com/ksmith1010/jf0x8orudyb9/wish/164745019
