Answer
We will assign unique numbers from 1 to 898 for 898 sophomores, 1 to 943 for 943 juniors, and 1 to 895 for 895 seniors. Then, we use MS Excel to generate random samples. The sample output for each of the three stratum is as follows:
a. Student number 90, 754, 921, 9 & 801 from sophomores
b. Student number 394, 620, 37, 719 & 83 from juniors
c.Student number 842, 286, 843, 563 & 3 from seniors
