Hello I need help with the below question, it is a math question.

An instructor for a SAT preparation course claims that the course will improve the test scores of students. The table shows the critical reading scores for 10 students the first two times they took the SAT. Before taking the SAT for the second time, the students took a course to try to improve their critical reading SAT scores. At a = 0.01, is there enough evidence to support the instructor's claim? 1 2 3 4 5 6 7 8 9 10 300 450 350 430 300 470 420 370 320 410 400 520 400 490 340 580 450 400 390 450
