Multiple Choice

In a multiple regression model involving 30 observations, the following estimated regression equation was obtained: $\hat { y }$ = 17 + 4x₁ - 3x₂ + 8x₃ + 8x₄

For this model, SSR = 700 and SSE = 100.The critical F value at $\alpha$ = .05 is

A reflex elicited by tapping the forehead between the eyebrows, leading to a transient blink response; often used to assess neurological function.

Achilles Reflex

A reflex action of the foot, elicited by a sudden stretch of the Achilles tendon, indicating normal function of the lower segment of the spinal cord.

Plantar Reflex

A reflex elicited by stroking the sole of the foot, used to assess the integrity of the spinal cord and higher brain centers; a normal response curls the toes, while the Babinski sign indicates neurological concerns.
