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 380 with a standard deviation of 20 on a standardized test. Assuming a bell-shaped distribution, where
would approximately 95% of the students score?
