Essay

The textbook derived the following result: $\hat { \beta } _ { 1 } \stackrel { p } { \longrightarrow } \frac { \sigma _ { X } ^ { 2 } } { \sigma _ { X } ^ { 2 } + \sigma _ { w } ^ { 2 } } \beta _ { 1 }$ Show that this is the same as $\hat { \beta } _ { 1 } \stackrel { p} { \longrightarrow }\beta _ { 1 } \frac { \sigma _ { w } ^ { 2 } } { \sigma _ { w } ^ { 2 } + \sigma _ { X } ^ { 2 } } \beta _ { 1 }$

Definitions:

3-Sigma

A statistical term that refers to three standard deviations from the mean, often used in quality control to represent a high level of quality or conformity.

Control Limits

Statistical boundaries defined in process control that identify the maximum and minimum values expected for a process to remain in control.

Inside Diameter

The distance across the inside circle of a cylindrical object or space, measuring from one inner edge directly across to the opposite inner edge.

Piston Rings

Circular metal components fitted into the grooves on the outer diameter of a piston in an internal combustion engine, designed to seal the combustion chamber, control engine oil consumption, and support heat transfer.
