Complete all of the following problems. Show all work and answer on a separate sheet! 1.) To help in estimating the number of customers for an amusement park bungee jump, the operators hired
a market research group to visit several similar parks that had bungee jumps. They recorded the number of
customers on a weekend day. Since the parks charged different prices for their jumps, the collected data
looked like this:
Price per Jump (in dollars) [15 20 25 28 30]
Number of Customers [25 22 18 15 14]
a.) In this situation, which variable makes sense as the independent variable and which as the
dependent variable?
b.) Plot these data on a coordinate graph.
c.) Does it make sense to connect the points on
your data plot? Explain your reasoning.

Which equation shows y= 3 4 x− 5 2 in standard form? a 4x−3y=10 b 3x−4y=10 c 3x−4y=−10 d 4x−3y=−10

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.
