Based on the table attached for the quality of life experienced by men and women 1 month after myocardial infraction answer the following: a) Where the groups in this study independent or dependent? Provide a rationale for your answer. b) t = -1.99 describes the difference between women and men post myocardial infarction (MI) for what variable? Is it significant? Discuss the meaning of this result in this study. c) Consider t = -2.74 and t = -2.31. Which calculated test statistic has the smaller p-value? d) Which t test statistic listed in the table had the largest p-value? What was the focus of this t-test, and were the results significant? Provide a rationale for your answer. e) What is df? Why is it important to know the df for a t test statistic? How do you calculate a df for a t-test and what is the df for this study? f) The authors report multiple df values in table VI. Why would different df values be reported? g) Does this study meet the assumptions for the t-test? Provide a rationale for your answer. h) What level of measurement is data that is analyzed by means and standard deviations? i) What does the t value for the Physical Component Score tell you about men and women post MI? If this results was consistent with previous research, how might you use this knowledge in your practice?
