Private adoptions cost significantly more than public adoptions, likely due to longer wait times, extra agency fees, and higher demand.
Based on the provided image, the survey indicates that the mean cost of adoption through private agencies is significantly higher than the mean cost through public agencies. The survey compared the costs of adoption for a sample of 16 adoptions through a public agency and a sample of 18 adoptions through a private agency. The mean cost for public adoptions was $21,045, while the mean cost for private adoptions was $22,840. This difference is statistically significant at the 0.05 level, meaning that it is unlikely to have occurred by chance.
The survey also notes that the standard deviations of the costs for both public and private adoptions are relatively small (approximately $835 for public adoptions and $1,545 for private adoptions). This means that the costs for individual adoptions are more likely to be clustered around the mean for each type of adoption.
Overall, the survey provides strong evidence that the mean cost of adoption through private agencies is significantly higher than the mean cost through public agencies. This difference is likely due to a number of factors, such as the length of time required for private adoptions, the additional fees associated with private agencies, and the higher demand for private adoptions.
