Mark each of the following as true or false and justify your response. True or False & explain reason for true or false: 1. Sample statistics for variables in a data set should only be calculated for a case-control study. 2. Results from studies should always be generalized to the entire population regardless of the sample. 3. Stratified analyses may reveal differences between groups. 4. Relative Risk (RR) may be calculated for retrospective and prospective studies. 5. If a variable...

Mark each of the following as true or false and justify your response. 1. If you fail to reject the null hypothesis, then the research hypothesis is false. 2. Independent variables may be linearly related. 3. A slope of 1.2 indicates that the independent variable changes 12 units for every 10 unit change in the dependent variable. 4. If a variable is normally distributed with a mean of 50 and a variance of 9, then approximately 68% of scores are...
