Adiver is exploring the waters of the great barrier reef.

a. she is currently-5 feet from the surface of the water and plans to explores a shipwreck that is at -75 feet from the surface. she then continues to moves to the surface at the same rate. how long will it take the diver to reach the surface?

b. when she is done exploring the reef, she ascends at a rate of 5 feet per minute. once she reaches a height of -30 feet, she must rest for 15 minutes to allow her body to adapt to the changing water pressure. she then continues to the surface at the same rate. how long will it take the diver to reach the surface?

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.
