To estimate the correlation coefficient based on the points (7,7) and (11,11), we will consider the relationship between the two points.
1. Both points lie on the line \( y = x \), indicating a perfect positive linear relationship.
2. A correlation coefficient of \( 1 \) indicates a perfect positive correlation.
Given that the two points are aligned in a perfectly linear fashion with a positive slope, the estimated correlation coefficient would be \( 1 \).
However, since \( 1 \) isn't one of your provided options, the closest option that suggests a strong positive correlation would likely be \( 0.9 \).
So based on the information, the best option to select is:
**0.9**
