Answer 1

Que.a

We use following methods to draw random sample.

1. List each name on a separate piece of​ paper; place them all in a​ hat, and pick five

2. Number the names from 1 to 739 and use a random number table to produce 5.

Que.b

You didn't provide random number table. I use following random number table.

Since population have 739 students. 739 is 3 digit number, hence we consider first 3 digits of random number.

Hence from first random number we get 614, Now we go down in first row. Second random number is 902 but it is greater than 739 hence we skip that number and go to next number. In this way we proceed until we get 5 random numbers.

Our sample include student with number 614, 503, 024, 206 and 204.
