A statistical study is going to randomly select five individuals from a group of 60 people. The researcher is planning to use the following random digit table (shown above) to select the 5 random individuals. Who will be the five subjects that will be selected for this study?

Select one:

19, 68, 71, 57, 33

19, 57, 33, 26, 57

19, 57, 33, 26, 10

19, 57, 33, 26, 6

QUESTION 2.

71546 05233 53946 68743 72460 27601

A researcher is planning to select random random birds to study today. There are currently 400 birds that are tagged with numbers and a radio tracking device. Using the random digit table above, which two birds will be studied today? Enter your answer in the blank provided (enter the bird numbers, separated by a comma).

Answer 1

1)

Let's start at the left and look at 2-digit groupings. We need 5 numbers to represent the 5 individuals, so the numbers need to be between 01 and 60 and we shouldn't pick the same number twice (we want 5 different individuals)

19 is acceptable

68 is not since it is greater than 60

71 is not since it is also greater than 60

57 is acceptable

33 is acceptable

26 is acceptable

85 is not acceptable

79 is not acceptable

57 is not acceptable since it is repeating

06 is acceptable

Thus, the five subjects are:

19, 57, 33, 26, 6

2)

Here we look at 3 - digit groupings with numbers between 001 and 400

Starting at left,

715 is not acceptable

460 is not acceptable

523 is not acceptable

353 is acceptable

946 is not acceptable

687 is not acceptable

437 is not acceptable

246 is acceptable

Thus, the two birds that will be studied today are tagged as numbers

353, 246
