Notice, if we do it this way, there will be less than a 1% chance that we are making a type 1 error. A type 1 error is that we're rejecting it even though it's true. Here, there's only a 1% chance, or less than a 1% chance, that we will reject it if it is true. The next thing we have to think about is what type of distribution we should think about. The first thing that rings in my brain is we only have 10 samples here. We have a small sample size right over here. We're going to be dealing with a t distribution and a t statistic.
