Suppose that in your precalculus class, the final grade is based on four categories. The categories are homework, tests, labs, and a final exam. The final average for the course is the weighted average of scores
earned in these categories with the following weights.
Category
Weight
Homework
20%
Labs
5%
Tests
10%
Final Exam
65%
Suppose you've earned the following grades on each of the categories so far:
Homework
89%
Labs
53%
Tests
53%
The final exam has not yet taken place. Is it possible for you to earn a 80% course average? If yes, what
score do you need to get on the final exam?
Round your answer up to the nearest whole number (between 0 and 100).
If it is not possible to earn a 80% course average, just enter DNE (which stands for "does not exist").
Your final exam score needs to be:
_%

In a study of the relationship between socio-economic class and unethical behavior, 129 university of california undergraduates at berkeley were asked to identify themselves as having low or high social-class by comparing themselves to others with the most (least) money, most (least) education, and most (least) respected jobs. they were also presented with a jar of individually wrapped candies and informed that the candies were for children in a nearby laboratory, but that they could take some if they wanted. after completing some unrelated tasks, participants reported the number of candies they had taken. it was found that those who were identiď¬ed as upper-class took more candy than others. in this study, identify: (a) the cases, (b) the variables and their types, (c) the main research question, (d) identify the population of interest and the sample in this study, and (e) comment on whether or not the results of the study can be generalized to the population, and if the ď¬ndings of the study can be used to establish causal relationships.
