State whether the following statement is true or false, and explain why. If the statement is false, state the true change. A high school reports that its students' SAT scores were down by 12% in one year. The next year, however, the test scores rose by 20%. The high school principal announces, "Overall, test scores have improved by 8% over the past two years." Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. The statement is true because 20-12-8 and the percentage improvement is given by the difference in the percentages of the increase and decrease. B. The statement is false because the reference values for the decrease and increase are not the same. The true improvement over the past two years is%. (Simplify your answer. Type an integer or decimal rounded to the nearest hundredth as needed.).
