A study was designed to 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 30 on a standardized test. Assuming a mound-shaped and symmetric distribution, in what 68% of the score?
