Marat540 [252]

Answer:

Choice B

The mathematical model that best fits the data is a polynomial of order 2 as shown on the attachment.

The predicted global mean temperature in 2015 is; 412.24

Step-by-step explanation:

The first step is to obtain a scatter plot of the data and then fit a trend line. A quadratic polynomial fits the data well considering the large value of the coefficient of determination of 0.9984.

To determine the global mean temperature in 2015 we substitute x with 14 in the quadratic model;

y = 0.4643(14)^2 + 0.7976 (14) + 310.07

  = 412.24
