Suppose that the national average for the math portion of the College Board's SAT is 547. The College Board periodically rescales the test scores such that the standard deviation is approximately 75. Answer the following questions using a bell-shaped distribution and the empirical rule for the math test scores.
B) What is the z-score for student with an SAT math score of 625? |
here as we know that z score =(X-mean)/std deviation
therefore z-score for student with an SAT math score of 625 =(625-547)/75=1.04
