Multiple Choice

Provide an appropriate response.
-For a certain system of three linear equations, the solution set is $\{ - 17 , - 8,6 \}$ , and $D = 8$ . Find the values of $D _ { x } , D _ { y }$ , and $D _ { z }$

• A) \(\mathrm { D } _ { \mathrm { X } } = - \frac { 8 } { 17 } ; \mathrm { D } _ { \mathrm { y } } = - 1 ; \mathrm { D } _ { \mathrm { z } } = \frac { 4 } { 3 }\)
• B) \(D _ { x } = - 64 ; D _ { y } = - 136 ; D _ { z } = 48\)
• C) \(D _ { x } = - 17 ; D _ { y } = - 8 ; D _ { z } = 6\)
• D) \(D _ { x } = - 136 ; D _ { y } = - 64 ; D _ { z } = 48\)

Definitions:

Random Error Term

Refers to the unpredictable and inevitable fluctuations or deviations in data or experimental results that cannot be attributed to the variables being studied.

Variance

A statistical measure that represents the average squared deviation from the mean, showing how data points are spread out.

Sample Correlation Coefficient

measures the strength and direction of the linear relationship between two variables in a sample.

P-Value

A measure in statistical hypothesis testing representing the probability of obtaining test results at least as extreme as the ones observed, assuming the null hypothesis is true.
