Question
dividing up the groups
56 volunteers:
28 in group a: carrot alpha followed by carrot beta
28 in group b: carrot beta followed by carrot alpha
the farmer, being a good statistician, decides he needs to randomize the groups to help reduce bias. he assigns a number between 1 and 56 to each students name. then he breaks out the random number app on his phone and generates the following sets of numbers.
76 12 44 79 71 23 00 97 59 53 55 55 40 84 44
06 78 39 89 37 33 30 43 26 52 92 77 92 83 46
73 12 29 78 90 74 08 76 63 49 84 48 31 77 89
73 39 89 49 89 92 44 10 26 19 07 22 11 24 54
- what should he do with the first two numbers in the list?
put student 76 and student 12 in the first group.
put student 20 (76 - 56) and student 12 in the first group.
ignore the 76 and put student 12 in the first group.

Step1: Identify valid number range
The farmer assigned numbers between 1 and 56 to 56 volunteers. Numbers outside this range are not valid for selection.
Step2: Analyze the first - two generated numbers
The first number is 76 which is greater than 56, so it is not a valid number for selecting a volunteer. The second number is 12 which is within the range of 1 - 56.
