Applying a FDR becomes necessary when we're measuring thousands of variables (e.g. gene expression levels) from a small sample set (e.g. a couple of individuals). A p-value of 0.05 implies that we are willing to accept that 5% of all

When a textbook does not explain something clearly, it is a good idea to look in another book. However, in the case of p-values, using another book may confuse you even more.

      on your experiment the most important result is the p-value, highlighted at left in the pink cell. Since you set your alpha value at 0.05, if the p-value is less than 0.05, you can say that there is a statistically significant difference between the means of your two trials. Note that in this example, p = 2.6 x 10-16, which is < 0.05, so the

Compare the P-value to your alpha level. If the P-value is less than or equal to alpha, you will reject the null hypothesis (H0) and conclude that the sample data support the alternative

However, once you calculate the test statistic, Excel can get the critical values and the P-values needed to complete the test. The functions used to get critical values and P-values are demonstrated here.
