A group of experimenters has 30 hummingbirds in a large container and needs to assign 10 to each of the three groups labeled A, B, and C for an experiment. They can capture the hummingbirds one at a time when the hummingbirds enter a side chamber in the container that is baited with food. Which of the following methods is most likely to result in three comparable groups of 10 hummingbirds each?
Answers
Answer:
answer should be D
Explanation:

Answer:
E.) Place each hummingbird in its own numbered container (numbered from 1–30) in the order that it was caught. Write the numbers from 1 to 30 on slips of paper, put the slips in a jar, and mix them well. Pick 10 numbers out of the jar. Assign the hummingbirds in the containers with those numbers to group A. Pick 10 more numbers for group B. Assign the remaining hummingbirds to group C.
Explanation:
This is the only method that provides truely random results. Using Simple Random Sampling.
A.) This is wrong because it uses a convenience sample
B.) Wrong because it involves you picking out which birds to assign to each group (Leading to bias)

B(n)=2^n A binary code word of length n is a string of 0's and 1's with n digits. For example, 1001 is a binary code word of length 4. The number of binary code words, B(n), of length n, is shown above. If the length is increased from n to n+1, how many more binary code words will there be? The answer is 2^n, but I don't get how they got that answer. I would think 2^n+1 minus 2^n would be 2. Please help me! Thank you!
Answers
Answer:
The additional words is \(2^n\)
Explanation:
Given
\(B(n) = 2^n\)
Required
Determine the additional words; i.e. \(B(n + 1) - B(n)\)
From the given parameters, we have that;
B is a function of n
Such that;
\(B(n) = 2^n\)
To calculate \(B(n+1)\), we simply substitute n + 1 for n
\(B(n) = 2^n\)
\(B(n + 1) = 2^{n + 1}\)
Applying laws of indices
\(B(n + 1) = 2^{n} * 2^1\)
\(B(n + 1) = 2^{n} * 2\)
\(B(n + 1) = 2(2^{n})\)
Calculating Additional Binary Code;
\(B(n + 1) - B(n)\)
Substitute values for B(n + 1) and B(n)
\(B(n + 1) - B(n) = 2(2^n) - 2^n\)
Express \(2^n\) as \(2^ n * 1\)
\(B(n + 1) - B(n) = 2(2^n) - 2^n * 1\)
Express 1 as \(2^0\)
\(B(n + 1) - B(n) = 2(2^n) - 2^n * 2^0\)
Factorize
\(B(n + 1) - B(n) = 2^n(2 - 2^0)\)
\(B(n + 1) - B(n) = 2^n(2 - 1)\)
\(B(n + 1) - B(n) = 2^n(1)\)
\(B(n + 1) - B(n) = 2^n\)
Hence, the additional words is \(2^n\)
