What happens to the distribution of the sample means if the sample size is increased?
the means does not change
What is the difference between ideal range and the range of tolerance?
Ideal range means the normal operating conditions, and range of tolerance means the extreme varied conditions in which operation can continue, without failure
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.
Will the mean of the sample means be equal to the population mean?
Most probably not. But it should be close to the population mean if various conditions are met: For example, the population should consist of independent, [nearly] identically distributed variables, the sample is not systematically biased (it does not have to be completely random).

Difference between quantitative and qualitative analysis?
Qualitative analysis means just to detect the presence of a substance in the sample while quantitative analysis is the determination of that substance i.e., in which amount it is present in the sample.

When testing for differences between two means the sample population are?
You are testing the difference between two means of independent sample and the population variance are not known. from those population you take two samples of two different size n1and n2. what degrees of freedom is appropriate to consider in this case
What is sample means?
Trying
