The Graduate Management Admission Test (GMAT) is a standardized exam used by many universities as part of the assessment for admission to graduate study In business. The average GMAT score is 547 (Magoosh website, January 5, 2015). Assume that GMAT scores are bell-shaped with a standard deviation of 100. Make sure to use the empirical rule to answer these questions.
a. What percentage of GMAT scores are 647 or higher?
b. What percentage of GMAT scores are 747 or higher (to 1 decimal)?
c. What percentage of GMAT scores are between 447 and 547?
d. What percentage of GMAT scores are between 347 and 647 (to 1 decimal)?
Let x: the GMAT scores
x follows Normal distribution with mean = 547 and SD = 100
convert the given x values to z scores, and by using standard normal table , we can find the corresponding percentages .

Problem 2-23 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. If required, round your answers to two decimal places. (a) What percentage of students have an SAT math score greater than 622? % (b) What percentage of students have...
