You should always decide whether you are going to use a one-tailed or a two-tailed probability before looking at the data.

As in the introductory example we will be concerned with testing the truth of two competing hypotheses, only one of which can be true.

The classical approach is based on standard deviations. This method compares the test statistic (Z-score) to a critical value (Z-score) from the standard normal table. If the test statistic falls in the rejection zone, you reject the null hypothesis. The p-value approach is based on area under the normal curve.
