b. and if a random sample of n = 6 students is selected and the first five selected are sophomores, what is the probability that the sixth student selected will be a freshman?
Answer:
A) 0.4
B) 0.4267
C) 0.356
Explanation:
A) There are;
32 freshmen and 48 sophomores.
Thus, total number of students = 32 + 48 = 80 students.
Thus;
P(first student selected will be a freshman) = 32/80 = 0.4
B) Since there are 6 students randomly selected with the first 5 being sophomore, then;
After 5 sophomore students selected, we have;
(80 - 5) = 75 students left
Also, we have 32 freshmen.
Probability of the 6th being a fresh man which is the next selection is;
P(6th being a freshman) = 32/75 = 0.4267
C) if 10 sophomore students join, then total number of students is now;
80 + 10 = 90 students.
Thus;
P(first student selected will be a freshman after 10 sophomore students join) = 32/90 = 0.356
According to the Rescorla-Wagner theory of conditioning, blocking occurs because... Group of answer choices the CS has already taken up most of the available associative strength. familiar stimuli are more difficult to condition. the CS gathers more associative strength than the US. the US has already taken up most of the available associative strength.
Answer:
Explanation:
How does the Rescorla Wagner model explain the blocking effect?
This effect was most famously explained by the Rescorla–Wagner model. The model says, essentially, that if one CS (here the light) already fully predicts that the US will come, nothing will be learned about a second CS (here the tone) that accompanies the first CS.Robert Rescorla and Allen Wagner were the first to realize what about classical conditioning? ... those in a vegetative state showed trace conditioning but those who were unconscious did not.According to stimulus substitution theory, after pairing the new stimulus with the existing conditioned stimulus it is possible to replace the first CS with the new stimulus. For instance, you have conditioned a rat to respond to a whistle as a signal that it is about to be fed.
According to the Rescorla-Wagner theory of conditioning, blocking occurs because CS has already taken up most of the available associative strength. The correct option is A. The Rescorla-Wagner model claims that blocking happens because the CS added in the second phase offers no fresh or prognostic information.
What did Rescorla and Wagner show about conditioning?The value of a paired trial as reinforcement decreases with increasing associative strength between the presented stimuli is a fundamental tenet of Rescorla and Wagner's model of associative learning.
Blocking and Unblocking predictions are one of the R-W model's most significant contributions. When a novel stimulus is presented alongside an established CS, blocking happens because the novel stimulus has no predictive value because it is novel.
Thus, the ideal selection is option A.

The struggle for equal rights is still ongoing. Minorities face many struggles in acquiring social, political, and economic equality. While de jure discrimination is easier to combat, de facto discrimination is very difficult to erase. The legacy of Jim Crow and other discriminatory practices can be seen today. The criminal justice system is heavily biased against minorities through both systemic and individual prejudices. For instance, Black defendants are more than 30% more likely to be sentenced to prison for the same crime committed by a similarly situated White defendant. This impacts opportunities not only for the individual, but also for their community and family. Minorities Make up approximately 30% of the population but make up around 60% of the prison population, even though minorities are no more likely to commit crimes than their white counterparts. Given these facts, what can be done
Answer:
Explanation:
While I feel I state the obvious; This stems from the institutionalized racism within our justice systems as well as our police and government officials. Educating ourselves is the biggest step, then educating others on this as well. From there, voting and calling our legislators is a good way to help. Advocating through social platforms if you have a large, or a small, is also a good way to help. We also need to demolish private prisons in America. That will do a lot for this particular cause.
I sadly believe that peaceful change is going to do much on this cause
Read through the five characteristics of qualitative research again. Based on these characteristics, describe the ways that a qualitative research report will differ from a more traditional experimental report prepared in accepted American Psychological Association (APA) format
Answer and Explanation:
Some of the characteristics of qualitative research include:
1. Natural setting
2. Researcher is key instrument
3. Multiple methods
4. Focus on participants
5. Emergent design
1. Natural setting: This means that qualitative researchers collect their data from the field ie where the participant is naturally dwelling(sometimes without the participant's knowledge of the researcher). This is different from an experimental research that involves bringing participants to a lab in order to manipulate dependent variables and observe them with independent variables and extraneous variables. An experimental research would therefore have to report the effect of the independent variable on the dependent variable while a qualitative research would report participants behavior given variables in his natural dwelling.
2. Researcher is key instrument: a qualitative researcher is the main instrument of research as he does not make use of third party source of data or data collected by someone else such as use of questionnaires, he observes the participants directly in the field. An experimental researcher on the other hand makes use of the results of his experiment, cause and effect relationship of variables, in getting his data for analysis. Therefore the qualitative researcher and experimental researcher will report different sources/methods of data collection in their research report.
Mickey joins a guerilla band fighting the governemnt in some far away country. While in leading a squad of insurgents, he orders the death of every inhabitant of a small hamlet reportedly friendly to the government. Mickey is eventually captured and extradited to the Hague to face trial.
The purpose of Mickey's attack on the village was to create a state of extreme fear and dread amongst other villages who might support the government. Under this circumstance, Mickey would be charged with the:________.
Answer: crime of terrorizing
Explanation:
Terrorism is defined as the use of unlawful violence in order to inculcate fear which is done to intimidate the government or coerce them to agree to certain terms which are usually religious, or political.
Since the purpose of Mickey's attack on the village was to create a state of extreme fear and dread amongst other villages who might support the government, then he'll be charged with crime of terrorizing.
