Answer:
See the attachments for the summary results and the specific coefficients used in the equations.
Step-by-step explanation:
(a) Data is entered in the appropriate table (as here or in a spreadsheet) or list (as in your graphing calculator). The technology is used to calculate the r and r² values along with the relevant coefficients.
(b) The best fit of these choices is provided by the quadratic model.
_____
A quartic model gives an r² value of 0.9996. That model is shown in the third attachment.
