1)
The sample mean x is a point estimate for the population mean µ.
2)
In tests of significance, it is possible to reject the null hypothesis and yet
still have a significant result.
If one rejects the null hypothesis at the 5% level, then there is a 5% chance
that you made the wrong decision.
4)
In the p-value approach, if p-value>a (the level of significance) we reject
the null hypothesis.
5)
If you fail to reject the null hypothesis at the 5% level, then the probability
that you are wrong is always 5%.
6)
A wider confidence interval gives a greater level of confidence than a
narrower one (when working with the same data).
7)

If the sample mean of a data set is 3.2 then the population mean must also

10)
The level of significance is the probability of rejecting the null hypothesis
Classical hypothesis testing can give different decisions than the P-value approach
even with the same level of significance, hypotheses and data?
