Complete Question:
Which of the following best describes how computing devices represent information?
Group of answer choices
A. A computer will either represent information as bits or bytes but not both.
B. A computer represents data as a byte which is either a 0 or a 1.
C. A computer represents data as bits which is either a 0 or a 1.
D. A computer represents information as bits which contain 8 bytes.
Answer:
C. A computer represents data as bits which is either a 0 or a 1.
Explanation:
A computer represents data (informations) as bits which is either a 0 or a 1. Bits is a short for binary digits and it is typically the smallest unit of representing data (informations) in computers; which is simply either a 0 or a 1. Also, these two (2) digits (0 or 1) represents a computer's logical state.
A value of 0 represents Off, False, No or Minus (-) while a value of 1 represents On, True, Yes or Add (+) in computer memory.
This ultimately implies that, a bit can only hold one of two values, either a 0 or a 1.
Additionally, bytes are made up of bits; one (1) byte is equal to eight (8) bits.
Answer to Question 1:
The behaviour of the students who hastily write what they consider a "C" level essay after being repeatedly told they can't make an "A" or "B" is a consequence of Reinforcement.
The answer, therefore, is D.
Explanation:
Reinforcement in behavioural psychology refers to the process of encouraging or entrenching a belief system or pattern of behaviour. It can also be defined as any stimuli which stimulate a thought pattern and engrains the probability of a specific response to a particular stimulus. Reinforcements are usually more effective when it comes from a person of perceived to be in a position of authority.
The high school students were verbally programmed by the instructor, who has the authority to mark their scripts, into thinking they will never be able to make an "A" or a "B". The result is that the students didn't even try to put in efforts that would have led to an A or a B because even if they did, the instructor has the power to ensure that no one score an "A" or a "B".
The challenge here is not that the students couldn't write "A" grade essays. In their mind, there was no point trying given that the ability lay with the instructor to ensure that what he said will happen. In any case, the instructors intended behavioural response was achieved.
2. The correct answer to the question of Acquisition and Extinction as indicated on the graph is B.
The strength of the response increases then decreases over time.
Acquisition happens when a neutral stimulus turns into a conditioned stimulus.
When a behavior begins to diminish or even disappear completely as a result of the gradual removal of a conditioned response, extinction is said to have occurred.
Cheers!
The conclusion that you will be able to reach if method I is used that cannot be concluded if method II is used is that the results can be generalized to the population as a whole.
In method I, the researchers decided to recruit volunteers. This sample includes people who do not exercise, people who exercise alone and people who exercise with a partner. On the other hand, method II will recruit participants at a community fitness center. Therefore, this sample will not include people who do not exercise. This means that method I will have a sample that is more representative of the general population.
Answer:
<u>The proportion of women who ran the marathon and had a finishing time less than Kathy's is 66% (rounding to the next whole)</u>
Explanation:
1. Let's review the information given to us to answer the question properly:
μ of finishing time for women = 259 minutes
σ of finishing time for women = 32 minutes
Finishing time for Kathy = 272 minutes
2. What proportion of women who ran the marathon had a finishing time less than Kathy's? Show your work.
Let's calculate the z-score for the finishing time for Kathy, as follows:
z-score = (272 - 259)/32
z-score = 13/32 = 0.41 (rounding to the next hundredth)
Using the z-table, now we can calculate the proportion of women who ran the marathon had a finishing time less than Kathy's:
p (z=0.41) = 0.6591
<u>The proportion of women who ran the marathon and had a finishing time less than Kathy's is 66% (rounding to the next whole)</u>
