There are 70 students in a classroom. A teacher wants to select 7 stud

1.	There are 70 students in a classroom. A teacher wants to select 7 students for 7 activities. Obtain a random sample with replacement using the following random numbers:274, 323, 923, 599, 667, 320, 910, 484, 786, 253, 009, 885, 115.
Answer» First of all, we will assign numbers 1 to 70 to the students in a classroom. Population size N = 70, a two-digit number. Hence, we consider only first two digits of random numbers and ignore the first two digits greater than 70. Random sample with replacement is to be obtained. Hence, we consider the repeated random numbers. The selected random numbers are : 27, 32, 59, 66, 32, 48, 25, 11. A random sample of 7 students is to be obtained. Therefore we select first seven random numbers from the above. Thus, random numbers of selected seven students are respectively 27, 32, 59, 66, 32, 48, 25, which is random sample with replacement.

Answer»

First of all, we will assign numbers 1 to 70 to the students in a classroom.

Population size N = 70, a two-digit number. Hence, we consider only first two digits of random numbers and ignore the first two digits greater than 70.

Random sample with replacement is to be obtained. Hence, we consider the repeated random numbers.
The selected random numbers are : 27, 32, 59, 66, 32, 48, 25, 11.
A random sample of 7 students is to be obtained. Therefore we select first seven random numbers from the above.
Thus, random numbers of selected seven students are respectively 27, 32, 59, 66, 32, 48, 25, which is random sample with replacement.
