The complete question is
Consider a researcher who is conducting final clinical trials to validate that a new treatment for anxiety is effective. This researcher is extremely focused on avoiding mistakes in concluding that this new treatment is effective when it really is not when conducting their research. What should this researcher do?
a. set a low alpha level
b. set a high alpha level
c. set a low sample mean
d. set a high sample mean
Solution
Option A
While carrying out multiple tests, alpha levels are set at low value. In this way value of alpha also reduces. The lower is the value of alpha, the lower will the chances of rejecting a null hypothesis. The chances of type II error increases, which makes it difficult to reject the null hypothesis
Null hypothesis in this case is "New treatment is effective"

Answer:
you could use the microarray technology to see which genes his cancer cells have increased, lessened, turned on, or turned off.
Explanation:
Microarray technology is a unique tool used almost exclusively in molecular biology, since it is able of counting hundreds or thousands of gene transcripts from a specific cell or tissue sample at the same time. Therefore based on the information provided within the question it can be said that in this scenario you could use the microarray technology to see which genes his cancer cells have increased, lessened, turned on, or turned off.
