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...

2. (2 True-False. Just say whether each statement is True or False – no need to justify your answer. 1. If the number of trials in the binomial distribution increases by 1 (and P equals .50), the probability of getting either of the most extreme possible outcomes (that is, 0 or N) is cut in half. 2. If the number of trials in the binomial distribution increases by 1 (and P does not equal .50), the probability of getting either of...
