A study was designed to investigate the effects of two variables - (1) a student's level of mathematical anxiety and (2) teaching method - on a student's achievement in a mathematics course. Students who had a low level of mathematical anxiety were taught using the traditional expository method.These students obtained a mean score of 420 and a standard deviation of 40 on a standardized test. Find and interpret the z-score of a student who scored 460 on the standardized test.
