**Title: Exploring Perceptions of Relationship Happiness Among Couples****Introduction:**Dr. Ferreira's research focuses on understanding how intimate couples perceive their happiness within their relationships. Each partner was asked to rate their happiness, and the data collected aims to identify whether men or women have a more positive view of their relationship.**Data Analysis:**- **Hypotheses:** - Null Hypothesis (H₀): There is no significant difference in relationship happiness ratings between men and women. - Alternative Hypothesis (H₁): There is a significant difference in relationship happiness ratings between men and women.- **Data Table:**| Couple ID | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | Mean | Standard Deviation ||-----------|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|------|-------------------|| Male | 12 | 10 | 15 | 8 | 14 | 18 | 6 | 9 | 7 | 14 | 11.3 | 3.92 || Female | 8 | 7 | 6 | 11 | 11 | 15 | 4 | 7 | 6 | 3 | 7.8 | 3.61 || Difference| 4 | 3 | 9 | -3 | 3 | 3 | 2 | 2 | 1 | 11 | 3.5 | 3.95 |**Explanation:**The table above presents the happiness ratings provided by each couple’s male and female partners, along with their respective means and standard deviations. The difference row highlights the gap between male and female ratings for each couple.**Conclusion:**To determine the significance of the observed differences, a statistical test such as a paired t-test can be performed. Based on the calculations:- **Decision:** If p-value < 0.05, reject the null hypothesis.- **Conclusion:** If the null hypothesis is rejected, it suggests that there is a statistically significant difference in how men and women view their happiness within relationships.

Given information, Sample mean of ratings given by men X¯M=11.3 Sample mean of ratings given by…

Secretary of State Roxana Tillerson is worried about malpractice at the 4 processing centers for Green Cards in the country. Green Card applications are given a grade g on a scale 0-100. They are assigned randomly to different centers and thus Tillerson expects all centers to have similar mean scores. She collects the data in the table. #applications 9360 67.27 15.29 1 9870 66.74 14.64 7020 66.94 15.14 3 5040 67.02 14.84 4 rows x 3 columns At this point she just wants to decide whether or not to initiate a deeper investigation into malpractice at all sites.
