What is sample and sample size means?
k
What happens to the distribution of the sample means if the sample size is increased?
the means does not change
The distribution of sample means is not always a normal distribution Under what circumstances will the distribution of sample means not be normal?
The distribution of sample means will not be normal if the number of samples does not reach 30.
Does the distribution of sample means have a standard deviation that increases with the sample size?
No, it is not.
The sum of the differences between sample observations and sample means is what?
always zero
Is it possible for two sample sets to have the same range but different means?
could a sample set have the same range but different means
Are sample means more variable than individual observations Are sample means more skewed than individual observations?
No, to both questions.
Can one treat sample means as a normal distribution?
Not necessarily. It needs to be a random sample from independent identically distributed variables. Although that requirement can be relaxed, the result will be that the sample means will diverge from the Normal distribution.
Why do most sample means differ somewhat from the population mean?
The sample is not a perfect representation of the population.
If a half life is 2000 years will a large amount of this radioactive sample be around for a long time?
Half-life of 2000 years means that after 2000 years, half of the sample will decay - so of course the other half of the sample is still around.Half-life of 2000 years means that after 2000 years, half of the sample will decay - so of course the other half of the sample is still around.Half-life of 2000 years means that after 2000 years, half of the sample will decay - so of course the other half of the sample is still around.Half-life of 2000 years means that after 2000 years, half of the sample will decay - so of course the other half of the sample is still around.

What does it mean for a sample to have a standard deviation of zero?
It means that there are is no variation from the mean. In other words, all values in your sample are identical.
