A sample gets information from a proper subset of the population.
A stratified sample is where you partition the population into two or more groups

and then take a random sample from each group.

An experiment is any study that seeks to answer a research question.
In a double blind study neither the researcher, nor the experimental subjects

know which individuals receive the treatment and which do not.
f)
The coefficient of determination gives the proportion of the change in the
response variable the can be attributed to the change in the explanatory variable and
the regressions line.
A wider confidence interval gives a greater level of confidence than a

narrower one (when working with the same data).
bo h)
If the sample mean of a data set is 3.2 then the population mean must also
be 3.2

As the sample size (n) increases, the standard deviation of x from that
sample decreases, this assumes the standard deviation is positive..oalugoq ad

j)
In the p-value approach, if p-value>a (the level of significance) we reject
the null hypothesis.
If you fail to reject the null hypothesis at the 5% level, then the probability

that you are wrong is always 5%.
The level of significance is the probability of rejecting the null hypothesis
