Answer:
Predictive validity.
Explanation:
As the exercise suggests with the Psychology Aptitude Test (PAT) scoring system; the predictive validity is a way of calculating how a determined score on a test predicts scores on a certain criterion measure. In other words, this is a correlation between tests and ratings; as shown in the example provided by the exercise: "Their scores were later compared to their performance in the introductory psychology course, and high scores on the PAT were related to high grades in the course".
Answer:
B) There is not sufficient evidence to support the claim that the true proportion is less than 21 percent.
Explanation:
According to a different source, these are the options that come with this question:
A) There is sufficient evidence to support the claim that the true proportion is less than 21percent.
B) There is not sufficient evidence to support the claim that the true proportion is less than 21percent.
C) There is sufficient evidence to support the claim that the true proportion is greater than 21percent.
D) There is not sufficient evidence to support the claim that the true proportion is greater than 21percent.
This would be the best way to explain what this conclusion means. The hypothesis states that more than 21% of the population suffers from professional problems due to extreme shyness. Moreover, the null hypothesis states that there is no meaningful relationship between two measured phenomena. If we "fail to reject" the hypothesis, this means that we do not have evidence that shows that the hypothesis is not true. Therefore, we can claim that there is not sufficient evidence to support the claim that the true proportion is less than 21 percent.
The 9th Amendment states that: "The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people."
It is, in effect, that even there are rights other than just the ones listed in the Bill of Rights and they can't be violated either.
