Answer:
b. variability of the estimates made from the data collected in the poll
Explanation:
A sample size tends to influence the precision of the estimates and power of the study. With the increase in the sample size of an opinion poll there is a decrease in the means of the standard deviation. This results in the reduction of the variability of the estimates which is made from the data collected in the poll. Large samples will have small margin of error.
This illustrates the importance of cognitive processes in classical conditioning
<u>Explanation:</u>
Cognitive science is the experimental research of the brain as an information processor. Cognitive analysts attempt to make up cognitive models of the information processing that runs on inside people’s brains, including observation, concentration, communication, thought, imagining, and awareness.
Cognitive analysts view it as necessary to see at the mental manners of an organism and how these impact behaviour. They follow the example of the behaviourists in favoring objective, controlled, scientific methods for investigating behaviour. They apply the results of their investigations as the foundation for creating thoughts about mental processes. In this mannens how the alcoholism make an impact behaviour is shown.
The mechanical energy of an object is equivalent to the sum of its potential and kinetic energy. If the helicopter is grounded, then its mechanical energy will be 20 J. If it is in the air, then its potential energy will be calculated using:P.E = mghAnd then added to the kinetic energy to obtain mechanical energy.
