Question

a) Make a scatter plot of the data in the table below. b) Does it appear that a linear model or a cubic model is the better fit for the data?

Answer 1

Hello

The answer to question A is option B.

You will have to carefully look at the scatter plot and the given table to see the correlation as well as deduce the scale used.

For the x-axis, one box represent 1 units while for the y-axis, one box represents 5 units.

Question B

Cubic model fits the data because it behaves as a polynomial function since it has more than one turn. A linear model or simple regression line works best is the line are in a straight line and are regressing.
