AI Thread Summary
To sample five cotton-top tamarins using a random number table, first assign numbers 1 to 80 to each tamarin. The provided random number table can be broken down into 18 two-digit numbers. Any numbers exceeding 80 should be discarded, leaving a selection of valid numbers. From the remaining numbers, choose five randomly to ensure a simple random sampling method. This approach allows for an unbiased selection of tamarins for the study of tail lengths.

okay guys this is the question:

A zoo has 80 cotton-top tamarins. Describe in detail how the random- number table given below could be used to select a sample of 5 of them, for a study of tail lengths.
8330 3992 1840 0330 1290 3237 9165 4815 0766
(5marks)

So I am not really sure where to go with this one, i can't see it being any type of systematic so it must be simple random sampling, but the issue is, there are nine groups of four numbers and I can't see a way to get these 36 numbers to relate back to the 80 tamarins.
Any help appreciated.

First assign numbers 1 to 80 to the 80 tamarinds.

You have 9 sets of 4 digit number:
8330 3992 1840 0330 1290 3237 9165 4815 0766

Break them into 18 groups of 2 digit numbers.
83 30 39 92 18 40 03 30 12 90 32 37 91 65 48 15 07 66

Drop any of those larger than 80.
30 39 18 40 03 30 12 32 37 65 48 15 07 66
Choose 5 of those in some way that preserves the randomness.
One way would be to choose tamarinds numbered 30, 39, 19, 40, and 03.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
