... We expect that the mean age for the US population is 44.54 years of age (although we know that this is probably incorrect). We can be 99% certain that the true population mean for age is between 43.37 and 45.71 years of age. In 99 out of 100 samples, our confidence interval would contain the true po ...

Hypothesis Testing
... When using dependent samples each observation from population 1 has a one-to-one correspondence with an observation from population 2. One of the most common cases where this arises is when we measure the response on the same subjects before and after treatment. This is commonly called a “pre-test/p ...

We start by assuming the “null hypothesis” which is that the test and control experiences are actually the same, and t ...
