This information is needed to solve #7 - 12. After picking cotton from the farm, it is
stored in rectangular "modules" which are later transported to a cotton gin for
processing. The average module carries 21 tons of raw cotton, out of which only
(30+ E)% is useful "lint" that can be used to make clothing and textiles. In 2017,
the USDA estimated that 2.1×107 bales of lint (each weighing 500 lbs.) were
produced in the country. Your region produced (B x C) bales, with an average yield
of (1000 - A) lbs./acre. There are (100+ A) gins in your region. The market price
of lint is 78 ¢/lb.

Find the regression equation.
Find the equation of the regression line for the given data. Then construct a scatter plot of the data and draw the regression line. (The pair of variables have a significant correlation.) Then use the
regression equation to predict the value of y for each of the given x-values, if meaningful. The number of hours 6 students spent for a test and their scores on that test are shown below.
