Multiple Choice

Apply Gaussian Elimination to Systems Without Unique Solutions
Use Gaussian elimination to find the complete solution to the system of equations, or state that none exists.
- $$\begin{array} { r } x + y + z = 7 \\x - y + 2 z = 7 \\2 x + 3 z = 14\end{array}$$

• A) \(\left\{ \left( - \frac { 3 z } { 2 } + 7 , \frac { z } { 2 } , z \right) \right\}\)
• B) \(\left\{ \left( - \frac { 3 z } { 2 } - 7 , \frac { z } { 2 } , z \right) \right\}\)
• C) \(\left\{ \left( - \frac { 3 z } { 2 } + 7,2 z , z \right) \right\}\)
• D) \(\left\{ \left( - \frac { 3 z } { 2 } - 7,2 z , z \right) \right\}\)

Definitions:

Null Hypothesis

A default hypothesis that there is no significant difference or effect, used as a starting point for statistical testing.

Level Of Significance

The probability of rejecting the null hypothesis in a statistical test when it is actually true; a threshold for determining the statistical significance.

Rejection Region

The range of values for which we reject the null hypothesis in hypothesis testing.

Level Of Significance

A threshold used in hypothesis testing, below which the null hypothesis is rejected.
