 It is important to note that, although `alpha = 0.05` is commonly used, this is an arbitrary choice and you should consider what is an appropriate type 1 error rate for your particular investigation.

-ii) Compares the means of these two samples with a *t*-test and extracts the *p*-value.

 3. Calculate the proportion of *p*-values that are smaller than 0.05.
