1. What are the similarities and differences between dependent [paired] and independent sam ple tests? [0.5 point}. Answe r: > Similarities: > Differences: Scenario An exercise researcher wants to com pare the energy expenditure associated with Wii cricket and Wii soccer. 30 participants were fitted with sensors that measured the amount of energy expenditure during a 15minute session. Energy expenditure scores [the dependent variable} were recorded for both conditions and served as the dependent variable for the analysis. Higher scores reflect higher energy expenditure and thus more calories burned. 2. Suppose that researchers wanted to compare the average energy expenditure scores between Wii cricket and Wii soccer. Write the research question for this problem [0.5 points}. Answe r: 3. Consider the hypotheses for the study. a. State the null hypothesis {in plain English rather than symbolic notation] {0.1 points). Answer: b. State the alternate hypothesis (again, avoid symbolic notation}. Note that you can choose whether to perform a one or twotailed test {0.1 points]. Answer: C. Provide a brief [one or two sentences] rationale for your decision to use one or two tailed tests {0.3 points]
