If a sample that originally contained Y grams of C has gone through two cloverleafs of decay how much C will be left?
To determine how much of a substance remains after two cloverleafs of decay, you first need to know the decay factor for each cloverleaf. Assuming each cloverleaf represents a significant reduction (often halving), the remaining amount of substance can be calculated as ( Y \times (0.5)^2 ) if each decay halves the amount. Therefore, after two cloverleafs of decay, you would have ( Y/4 ) grams of C left.

In basic statistics what is sample size and effective sample size?
sample size refers to the collection of data by only a selected size of te population through the process of sample surveys and sampling methods used in collecting data.

What is the relation between a t-test value and the sample variance?
The t-test value is calculated using the sample mean, the population mean, and the sample standard deviation (which is derived from the sample variance). Specifically, the formula for the t-test statistic incorporates the sample variance in the denominator, adjusting for sample size through the standard error. A smaller sample variance typically results in a larger t-test value, indicating a greater difference between the sample mean and the population mean relative to the variability in the sample data. Thus, the relationship is that the t-test value reflects how the sample variance influences the significance of the observed differences.
If a sample of DNA contained 20 percent cytosine what percentage of guanine would be in this sample and what percentage of adenine would be in the sample explain?
Umm I'll have to say that your a retard for not knowing it so tuff nubbs who ever made this is stupid because you spelled some words wrong.. The above answer is incorrect, and on a very low evolutionary rung. The correct answer is that with the amount of data provided, it is impossible to tell. If the answer isn't known, it is best to not answer.
What is the difference between sample and sample size?
a sample is a sample sized piece given... a sample size is the amount given in one sample

After 36.9 years a sample of hydrogen contains one-eighth the amount it contained originally what is the half-life of the isotope?
The half-life of the isotope in question is 12.3 years. This can be calculated by dividing the time it took for the sample to decrease to one-eighth its original amount (36.9 years) by 3, which represents the number of half-lives it took to reach that point.
What do you call a sample that goes through?
A sample that goes through a testing or analysis process is often referred to as a "test sample" or "analytical sample." This sample is typically prepared to assess its properties, quality, or composition. In scientific contexts, it can also be called a "specimen" or "representative sample," depending on the specific application and methodology used.
