Answer:

The test Joe should do is a Left-tailed test

Explanation:

From the question we are told that

The null hypothesis is
H_o : \mu = 37

The alternative is
H_a : \mu < 37

Here looking at the alternative hypothesis we see that
\mu < 37 , this tell us that the test is a Left-tailed test , it tell us that the value we are considering is at left side of the area under the normal curve
