Neuroleptics are type of drugs that help the brain in processing the following: B. Dopamine.
<h3>What is a drug?</h3>
A drug can be defined as a type of chemical substance that is designed and developed to improve and provide wellness and healing to a sick person.
<h3>What is a brain?</h3>
A brain can be defined as a delicate internal organ of soft-nerve tissue that is primarily found within the skull of vertebrates, and it's mainly responsible for the coordination of nervous activities, sensation and intellect in living organisms.
Based on medical records and information, we can infer and logically deduce that neuroleptics are type of drugs that help the brain in processing dopamine levels in a living organisms, so as to enable them:

Complete Question:
Neuroleptics are drugs that help the brain process which of the following?
A. Norepinephrine
B. Dopamine
C. Epinephrine
D. Serotonin
 
        
             
        
        
        
The standard error of the difference of sample means is 0.444
From the complete question, we have the following parameters
<u>Canadians</u>
- Sample size = 50
- Mean = 4.6
- Standard deviation = 2.9
<u>Americans</u>
- Sample size = 60
- Mean = 5.2
- Standard deviation = 1.3
The standard error of a sample is the quotient of the standard deviation and the square root of the sample size.
This is represented as:

The standard error of the Canadian sample is:

So, we have:

The standard error of the American sample is:

So, we have:

The standard error of the difference of sample means is then calculated as:

This gives


Take square roots

Hence, the standard error of the difference of sample means is 0.444

Answer:
P(A or B)=0.6425
Explanation:
To find P(A or B), plug your values for A and B into the equation:
P(A or B)= P(A) + P(B) - P(A and B)
