Answer:

A. 5

B. 29, 16, 24, 20, and 15

Step-by-step explanation:

The sample size is 5.

Each student is assigned a two digit number, so split the random digit table into two digit numbers.

29, 62, 16, 65, 83, 62, 96, 61, 24, 68, 20, 34, 51, 40, 15, 04, 01, 43, 57, 13, 03, 98, 00, 30, 24

Identify the first 5 unique numbers between 12 and 30.

29, 62, 16, 65, 83, 62, 96, 61, 24, 68, 20, 34, 51, 40, 15, 04, 01, 43, 57, 13, 03, 98, 00, 30, 24
