$\text { Figure } 5.2$
-Based on the Excel output in Figure 5.2,you should conclude that the estimated sample regression function is

• A)statistically significant because 65.21 > .05.
• B)statistically significant because 1.465E - 10 < .05.
• C)statistically significant because 7.092E - 30 < .05.
• D)statistically significant because 25.42 > 1.96.

Monozygotic Twins

Twins that result from the division of a single fertilized egg, sharing all of their genetic material and typically having nearly identical appearances.

Dizygotic Twins

Also known as fraternal twins, they are two offspring that develop from separate eggs and are fertilized by separate sperm, making them genetically unique from each other.

Common Family Environment

The shared atmosphere, practices, and dynamics within a family that all members experience, influencing their development and behaviors.
