Find the lowest score (X) using normal distribution.
Finding an X score. All Bright University will consider an applicant for its MBA program who scores 95 percent or higher on the GMAT exam. The mean and standard deviation, respectively, for this test are 578 and 94. What is the lowest score (X) that an applicant could earn to be considered for the MBA program at All Bright University? Round off the answer to the nearest whole number. (Hint: Use the formula X = z times the standard deviation + the mean.)
