The following graph is an ogive of a standardized​ test's scores. The vertical axis in an ogive is the cumulative relative frequency and can also be interpreted as a percentile. Complete parts a through c.   A graph of a curve titled “Percentile Ranks of Test Scores” has a horizontal axis labeled “Test Score” from 80 to 180 in increments of 10 and a vertical axis labeled “Percentile” from 0 to 100 plus in increments of 10. From left to right, the curve rises at an increasing rate from the point (80, 0) to (130, 50), and rises at a decreasing rate from (130, 50) to (180, 100). Two other points the curve passes through are (110, 10) and (150, 90). Part 1 (a)  Find and interpret the percentile rank of a test score with a value of 130.   A test score of 130 corresponds to the enter your response hereth percentile rank since this percentage of test scores are greater than or equal to less than or equal to less than greater than a test score with a value of 130.
