question 102

Multiple Choice

In a regression model involving 30 observations, the following estimated regression model was obtained: $\hat { y }$ = 60 + 2.8x1 + 1.2 x2 - x3. For this model, total variation in y = SST = 800 and SSE = 200. The value of the F-statistic for testing the validity of this model is:

• A)26.00.
• B)7.69.
• C)3.38.
• D)0.039.

Definitions:

Confining Pressure

The pressure applied equally in all directions at any given point within the earth’s crust, often affecting rock properties.

Compression

is the application of force that presses matter together, reducing its volume or causing deformation.

Tension

A force that pulls materials apart, causing stress or strain in geological contexts, such as the stretching of the Earth's crust.

Shear

A strain in materials characterized by slippage along parallel planes, often related to faults and shear zones in geology.
