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. t=-3.15 describes the differences between women and men for the mental health variable. It has the smallest p value, at p-0.002 and that is considered significant because the p=0.002 is smaller than alpha that was set at 0.05 for this study. Small p values indicate significant findings.
3. Is t = –1.99 significant? Provide a rationale for your answer. Discuss the meaning of this result in this study. T=-1.99 describes the difference in health functioning between men and women after an MI. t=-1.99 is significant because it’s p value (0.049), is still smaller than alpha that was set at 0.05 for this study. The meaning of this result in this study is that the quality of life measures in regards to health functioning show a significant result. This finding indicates that women had a mean of 17.9 with an sd of 4.1, and men had a mean of 19.3, with an sd of 4.6. Results support the study and findings that, “women rate lower levels in physical and psychological dimensions of quality of life”
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.
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 result mean?
t= -2.50, p=0.01; t= -2.54, p= 0.007. t=-2.54 has a smaller p value at p=0.007 than t=-2.50 with p=0.01. The smaller p value...
