Explanation / Answer

1) FROM 1 TO 444

2)

1) Select the random digit with length k which is same as thelength of the population size.

2) Omit 0, 00,000, … since no one in the population beassigned with the number 0.

3) Omit the repeated numbers if any in the case of randomsampling with replacement.

4) Omit those random numbers which are greater than the size ofthe population.

So in this case we have to choose random digits of length 3 fromthe table and those numbers which are less than or equal to N =448.

So the required sample is,

138, 159,052,087,359,275,186,369,154,072
