question 8

Essay

Write the following three linear equations in matrix format $A x = b$ , where $\boldsymbol { x }$ is a $3 \times 1$ vector containing $q , p$ , and $y , \boldsymbol { A }$ is a $3 \times 3$ matrix of coefficients, and $\boldsymbol { b }$ is a $3 \times 1$ vector of constants. q = 5 +3 p - 2 y
q = 10 - p + 10 y
p = 6 y

Definitions:

Alpha Levels

A threshold value that determines the significance level of a statistical test, representing the probability of rejecting a true null hypothesis (committing a Type I error).

Two-tailed Test

A statistical test that considers the possibility of both positive and negative differences or effects.

Research Hypothesis

A specific and testable prediction about the relationship between two or more variables.

Alternative Hypothesis

A hypothesis that contradicts the null hypothesis, suggesting that there is a statistical effect or a significant difference in the population.
