SCENARIO
You are a Marriage and Family Therapist. In your practice, you’ve noticed that children seem to be dramatically influenced by their parent’s marital relationship. You think that changes in marital relationship can be predictive of a child’s overall life satisfaction. In order to test this, you collect data from both children and their parents (n=20). You give the children in your study the Child Psychological Wellbeing Inventory (CPWI) and their parents the Marital Satisfaction Survey (MSS). Using the data below, answer the following questions.

What is the research question?
Is there a relationship between children who seem to be dramatically influenced by their parent’s marital relationship?
Calculate the expected CPWI for MSS scores of 102 and 128.
MSS | Predicted |
102 | 106.043 |
128 | 127.775 |
Given that this is a bivariate analysis, what is the correlation coefficient (r)?
r | 0.903 |
Report and interpret the 95% confidence interval for the correlation.
confidence interval | |
95% lower | 95% upper |
0.6384 | 1.0333 |
The 95% confidence interval for the correlation is between 0.6384 and 1.0333. There is a 95% chance that the true slope of the regression line lies within this interval.
Please give me a thumbs-up if this helps you out. Thank you!

Maintaining a healthy weight is important for women’s health. Some physicians recommend being back to your pre-pregnancy weight six months after giving birth. Public health officials are interested in whether this is a realistic goal. Do the women in North Carolina weigh more than their pre-pregnancy weight six months postpartum? In other words, is the six months post-pregnancy weight greater than their pre-pregnancy weight? Use a paired samples t-test to compare pst6wght (variable 1) and prewght (variable 2). This uses...
Please label and show each step. Four different paints are advertised to have the same drying times. To verify the manufacturer’s claim, seven samples were tested for each of the paints. The time in minutes until the paint was dry enough for a second coat to be applied was recorded. Below are the results which may be imported into MSExcel for analysis: (Assume the populations are normally distributed, the populations are independent and the population variances are equal) Paint 1...

Scenario 1 As the food court manager at the Mall of Elbonia, you want to determine how much time customers spend at the mall at different times of the week (for example: midweek, day; midweek, evening; weekend, day; weekend, evening). Last week, the mall survey staff administered a random survey to mall visitors by selecting customers as they were leaving the mall. One of the questions asked was how much time the customer had spent in the mall on that...
