Answer:
The researcher is trying to demonstrate a scientific experiment called <u><em>Dichotic Listening</em></u>
Explanation:
<em>Dichotic listening</em> is the listening to different acoustic events presented to each ear simultaneously. Most commonly, <em>the acoustic signals are speech, such as digits, words, consonant-vowels, or sentences.</em>
This test is used to carry out behavoural test of <em>Central auditory processing</em> which help to determine which ear (left ear or right ear ) has the <em>best advantage in listening</em>.

B. Cooperative federalism has been practiced in the US since 1860.
Cooperative federalism, or the concept of federalism in which local, state, and federal governments work together to create policies, replaced dual federalism in the 1930s.
In an attempt to reduce the likelihood of a type ii error, the experimenter proposes to recruit a very large group of participants.
In statistical hypothesis testing, a Type I error is actually an incorrect rejection of the true null hypothesis (a.k.a. a "false positive" result or conclusion; e.g., "Innocent person convicted ing"). Rejection of one actually false null hypothesis (also called a "false negative" result or conclusion, e.g. "guilty party not convicted").
Many statistical theories revolve around minimizing one or both of these errors, but unless the outcome is determined by a known and observable causal process, either of these errors can be completely quantified. It is statistically impossible to eliminate You can improve the quality of the hypothesis test by choosing a lower threshold (cutoff) and changing the alpha (α) level. Knowledge of type I and type II errors is widely used in medicine, biometrics, and computer science.
