Name: : HLT 362 Date: 01/20/2013 □ EXERCISE 29 Questions to be graded 1. Were the groups in this study independent or dependent? Provide a rationale for your answer. The two groups were independent because they were formed based on gender (male/Female) with no intent to match subjects on any variable. The men and women selected for the experiment did not share any relationship nor lived in the same location. 2. t = −3.15 describes the difference between women and men for what variable in this study? Is this value significant? Provide a rationale for your answer. In this study, t= -3.15 describes the mental health variable. Yes it is significant because they are the variable being tested since the p value is 0.002 and the alpha is 0.05, the difference can cause the null hypothesis to be rejected. 3. Is t = −1.99 significant? Provide a rationale for your answer. Discuss the meaning of this result in this study. Yes t = -1.99 is significant because the p= 0.049 value is smaller than alpha (a) that was set at 0.05 for this study. From the study, this means that there is a significant difference between the results obtained from men and women since this is one of the values that allows the selected hypothesis to be correct, the significance is support to the performed experiment. 4. Examine the t ratios in Table VI. Which t ratio indicates the largest difference between the males and females post MI in this study? Is this t ratio significant? Provide a rationale for your answer. The mental health t ratio of t = -3.15 ratio indicates the largest difference between the males and females post MI in this study. This t ratio is significant since it is causing the p value to be significantly low, less than the alpha 0.05 set for the study. 5. Consider t = −2.50 and t = −2.54. Which t ratio has the smaller p value? Provide a rationale for your answer. What does this
