Scores on required state math tests along with school attendance (days) were collected for 72 sixth grade students. The standardized z-scores of the test results and those of the students' attendance days were calculated and the pairs multiplied together. The sum of these 72 products was 57.15 . Based on this sum, what can you conclude about the correlation between math scores and days of attendance?
