There are 50 people in a class. The teacher wants a random sample of 10 students. She numbers the students consecutively (1, 2, 3, 4, . . . 50) and uses the random number  able to sample 10 cases without replacement. She starts on the first line of the table and uses it like a book, moving from left to right on each line. She divides each four-digit random number into two two-digit numbers. If the first number were 1273, she would read it as 12 and 73. List the numbers of the 10 cases in her sample.
