2952 | 6641 | 3992 | 9792 | 7969 | 5911 | 3170 | 5624 |
4167 | 9524 | 1545 | 1396 | 7203 | 5356 | 1300 | 2693 |
2670 | 7483 | 3408 | 2762 | 3563 | 1089 | 6913 | 7991 |
0560 | 5246 | 1112 | 6107 | 6008 | 8125 | 4233 | 8776 |
2754 | 9143 | 1405 | 9025 | 7002 | 6111 | 8816 | 6446 |
Draw a sample of 10 three-digit numbers which are even numbers
Solution
There are many ways to select 10 random samples from the given Tippets random number table since the population size is three-digit numbers
Here the door numbers must be even
i.e The unit digit must be even.
Here we consider column-wise selection of random numbers starting from first column.
So the first sample is 416 and other 9 samples are 056, 664, 952, 748, 524, 914, 154, 340 and 140.
