Hello. This question is incomplete. The full question is:
"A psychology professor wants to know whether verbal ability is related to memory quality in current first-year students at her small college. Participants in the study (first-year students at her college) complete an online memory task. The students are first shown a list of 60 words. Next they are shown a list that includes five new words that are conceptually similar to words on the original list. Then they are asked to identify the words on the second list that appeared on the original list. She uses the percentage of new but conceptually similar words that were mistakenly thought to be on the original list as her measure of memory quality. She also asks the students to report several characteristics such as their age, gender, and verbal SAT score.
Which of the following are variables in the study? Check all that apply. The students' verbal SAT scores The students' percentage of words that were correctly recognized on the original list The number of students participating in the survey."
Answer:
The student's verbal SAT scores
The student's percentage of words that were correctly recongnized on the original list.
The number of students participating in the survey.
Explanation:
Within all scientific research, variables (dependent and independent) can be verified. These variables correspond to the number of factors that can take on value within the experiment and dissolve results for the research to be completed.
Accordingly, we can see that the variables of the experiment shown above are:
- The student's verbal score in the SAT: presents a value and shows the difference between the students allowing a comparison to be made.
- The percentage of words of the student that were correctly refilled in the original list: Also assumes a value and shows a result that is directly related to the veracity of the hypothesis of the study:
- The number of students who participated in the study: It also assumes a value and will allow calculations and graphs to be made to show the results.

Answer:
The opportunity cost is the value of the Free ticket fee, the pleasure you would derive from going to your favorite venue, and the joy in seeing your favorite artist.
Explanation:
Opportunity cost is defined as the value or benefit of the forgone alternative in the course of making a decision. In this case, you are either faced with enjoying yourself at the event where your best artist will be performing at your favorite venue and at no cost and then performing badly on your ECON test on Friday, or sit back and study on Thursday so you can pass your test and then forget the event. Hence once you choose to study, the opportunity cost is the value of the ticket fee, the pleasure you would derive from going to your favorite venue, and seeing your favorite artist. Missing an autograph from your favorite artist can also be considered part of the opportunity cost.
