The two-sided alternative hypothesis is appropriate in this case, the reason being we are asked "does the data indicate that the average body temperature for healthy humans is different from 98.6◦........?".
The test statistic is:
Z= \frac{\bar{X}-\mu}{ \frac{s}{ \sqrt{n} } }} =-5.47
Using an inverse normal table, and halving \alpha for a two-tailed test, we look up p=0.5-\alpha/2=0.5-0.005=0.495 and find the critical value to be Z = 2.5758.
Comparing the test statistic Z = -5.47 with the rejection region Z < -2.5758 and Z > 2.5758. we find the test statistic lies in the rejection region. Therefore the evidence does not indicate that the average body temperature for healthy humans is different from 98.6◦.
