Question

QUESTION #9 (15 marks) How can engaged couples improve their chances of a happy marriage? A study selected 19 couples and tested the quality of their communication skills 3 months before marriage. Leading up to the marriage, the couples were then asked to participate in a communication skills course aimed at strengthening their skills. Three months after their marriage they were then tested again using the same quality measurement scale (higher scores mean better quality of communication). Since this study was a pilot test of the communication skills course, the researchers were not sure if they intervention would improve their communication skills or not. What conclusion can be made? Test at an alpha at 0.05 and use all the steps of hypothesis testing for full marks. Table 5.
