Keegan’s potw solution

  1. 1. Keegan’s POTW Solution<br />
  2. 2. The easiest way to complete this problem is to use a quartic regression equation to find the value of P(0).<br />
  3. 3. To do a quartic regression, you put the points into STAT.<br />
  4. 4. After the points are added, you can go to StatCALC to <br />Calculate the quartic regression.<br />
  5. 5. This is the equation for the quartic regression.<br />
  6. 6. With a R squared value of 1, this quartic is the best fit line for the points.<br />
  7. 7.
  8. 8. Since e=2.5 from the<br /> regression equation, <br />you know that P(0)=2.5<br />
