Does a small sample of Carbon-14 have the same activity as a large sample of Carbon-14?
No and yes. It depends on the way you define activity. Carbon-14 undergoes radioactive beta decay. The activity of Carbon-14 is given in terms of disintegrations per minute per gram of carbon. So, if you have a 100 gram sample and a 1 gram sample, there will be 100 times more disintegrations per minute with the larger sample. But typically, we are more interested in the time it takes a certain percentage to decay. Time values like half life will be the same for large and small samples.
What else can I help you with?
Why is a large sample better than a small sample?
A large sample will reduce the effects of random variations.
What is the weight of mag chloride?
It depends on how large or small your sample is.
Will a large sample size and a small sample variance produce the largest value for the estimated standard error?
no
What does it means if the standard deviation is large?
that you have a large variance in the population and/or your sample size is too small
Explain the differences between a sample and a population?
A sample consists of a small portion of data when a population is taken from a large amount.
Which of the following samples will produce the largest value for the estimated standard error?
A small sample size and a large sample variance.
What set of sample characteristics is most likely to produce a significant t statistic?
a small mean difference and large sample variances
What is used to create a large sample of DNA for testing for a small sample of DNA?
A technique called polymerase chain reaction (PCR) is used to create a large sample of DNA from a small sample. PCR amplifies specific regions of DNA by making millions of copies, allowing for further analysis and testing on the amplified DNA.
Does one ml have the same density of 15 liters?
Any sample of the same substance has the same density,no matter how large or small the sample is.
What is the method that creates a large sample of DNA for testing from a small sample of DNA?
That would probably be polymerase chain reaction or PCR for short.
What combination of factors will produce the smallest value for the standard error?
A small sample and a large standard deviation
How reliable is drawing a conclusion based on too small a population sample?
Drawing a conclusion based on too small a population sample is not reliable because the sample may not accurately represent the entire population, leading to biased or inaccurate results. It is important to use a sufficiently large and diverse sample size to ensure the validity and generalizability of conclusions.
