Class mates discussion:

A researcher wants to test out a new drug to see whether it can decrease the symptoms of Alzheimer’s Disease in participants 65 and older. He measures the symptoms of Alzheimer’s before and after the drug has been administered. The expectation is that the symptoms of Alzheimer’s decrease after the drug administration. 
Null Hypothesis is: H0 : symptoms of Alzheimer’s after drug intake ≥ symptoms of Alzheimer’s before drug intake ( in other words symptoms remain the same or are greater after drug intake)
Alternative Hypothesis: H1 : symptoms of Alzheimer’s after drug intake < symptoms of Alzheimer’s before drug intake ( in other words, symptoms of Alzheimer’s after drug intake are less than symptoms of Alzheimer’s before drug intake  Type I Error:?  Type II Error:?  Directional or Non-Directional:?
