Left-Tailed Test Rejects Null Hypothesis at 0.05 Level

[JocquettaLARuex]

In a left-tailed test, the value of the test statistic is -2. If we know the shaded area is 0.03,
then we have sufficient evidence to reject the null hypothesis at 0.05 level of significance.

Hi there,

How does the area of the shaded region relate to a p-value in hypothesis testing? In a left-tailed test is the area we look at the area to the left or the area to the right?
