Admission to a certain university is determined by an entry exam. The scores of this exam are Normally distributed with a mean of 400 and a standard deviation of 60. Only students who score in the top 3% will be offered admission. A student scores 425 on the entry exam. Choose the most accurate statement. O a. The top 3% is defined with a score less than or equal to 512.8, so she will be admitted. O b. The top 3% is defined with a score greater than or equal to 512.8, so she will not be admitted. O c. The top 3% of all students have scores greater than or equal to 520, so she will not be admitted. O d. The top 3% of all students have scores greater than or equal to 460, so she will not be admitted.
