Samara is doing research into factors that make

engineering students more likely to persist through their program.  Let’s assume she knew the average GPA for

students in this program was 3.20, with a standard deviation of 0.80. To

explore the situation, she began by accessing information about the population

of GPAs for these students.  Suppose she

wanted to know which GPA would put a particular student in the bottom 10% of

the distribution.  Which equation should
