The dot plots below show the weights of the players of two teams: two dot plots are shown one below the other. the top and the bottom plots have the title team e and team f respectively. below the line for each dot plot is written weight followed by pounds in parentheses. the markings on each line are from 120 till 140 at intervals of 1. for the top plot there are 2 dots each for 130 and 139 and 1 dot each for 126, 127, 132, and 135. for the bottom plot there are two dots each for 120, 121 and 126 and 1 dot each for 123, and 128. based on visual inspection of the dot plots, which team appears to have the larger mean weight? not enough information is available to draw a conclusion. both groups are similar. team f team e

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.
