Problem 1:
A 2012 study investigated the impact of psychological stress on men's judgments of female body size. The men were randomly assigned to one of two groups; one group was assigned to participate in a stressful task while the other group did not take part in the task. Then the men were asked to rate the attractiveness of female bodies varying in size from emaciated to obese.
a. What are the cases in this study?
b. Briefly explain why this is an experiment and not an observational study.
c. Identify the explanatory variable in this experiment.
d. Identify the response variable in this experiment.

Identify the use of appropriate experiment e Page(s) 9-10 In a study published in the journal Environmental Science and Technology in 2001, scientists were testing the endocrine disruptor hypothesis, which states that certain chemicals can interfere with hormone regulation in many organisms, leading to disorders such as the feminization of males. The scientists used juvenile fish and exposed them to either tap water or varying concentrations of treated sewage effluent (containing an array of chemicals). For this experiment,...
