Solve the problem.The paired data below consist of the costs of advertising (in thousands of dollars) and the number of products sold (in thousands). (i) Use a graphing calculator to fit a linear sequence regression function an = an + b to the data, where n is the cost of advertising (in thousands of dollars) and an is number of products sold (in thousands). (ii) Use this function to estimate the number of products sold if the cost of advertising is $6000.
A. (i) an = 2.79n + 55.8;
(ii) 72.54 thousand products
B. (i) an = 3.02n + 55.8;
(ii) 79.24 thousand products
C. (i) an = 5.79n + 94.3;
(ii) 16,795.8 products
D. (i) an = 2.73n + 34.8;
(ii) 69.54 thousand products
