Answer
(a) See graph.
(b) $y = 0.0098x - 19.118$
(c) $y = 0.0003x^2 - 1.0203x + 997.9$
Work Step by Step
(a) Using the data, we can make a scatterplot as shown in the figure.
(b) A regression line can be found as $y = 0.0098x - 19.118$ as shown in the figure.
(c) We can find a quadratic curve that captures the trend of the data as $y = 0.0003x^2 - 1.0203x + 997.9$ as shown in the figure.
