Can anybody PLEASE explain me this part in FA P54.

If the 95% CI for a mean difference between 2 variables includes 0, then there is no signicant difference and H0 is not rejected.

If the 95% CI for odds ratio or relative risk includes 1, H0 is not rejected.

If the CIs between 2 groups do not overlap statistically signicant difference exists.

If the CIs between 2 groups overlap usually no signicant difference exists.


The bold part is what i am confused. :(:rolleyes:

Thanks for the help.
