Question 2
A study was designed to investigate the effects of two variables - (1 ) a students level of mathematical anxiety and (2 ) teaching method - on a students 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 480 with a standard deviation of 20 on a standardized test. Assuming no information concerning the shape of the distribution is known, what percentage of the students scored between 440 and 520? A) at least 75 B) approximately 95
C) at least 88.9 D) approximately 68
