question 236

Multiple Choice

Solve the system.
$\begin{array} { l } \frac { 3 } { x } + \frac { 1 } { y } = \frac { 16 } { 35 } \\\frac { - 8 } { x } - \frac { 6 } { y } = - \frac { 26 } { 35 }\end{array}$

• A) \(\{ ( - 7,5 ) \}\)
• B) \(\{ ( 5 , - 7 ) \}\)
• C) \(\{ ( 35 , - 7 ) \rangle\)
• D) \(\{ ( - 5,7 ) \}\)

Definitions:

Null Hypothesis

A statement that there is no difference or effect, typically to be tested against an alternative hypothesis proposing a difference or effect.

Significance Level

The probability of rejecting the null hypothesis when it is actually true; a threshold chosen by the researcher to indicate the level of evidence needed to reject the null hypothesis.

Kruskal-Wallis Test

A nonparametric statistical test used to compare three or more independent samples to determine if they originate from the same distribution.

P-value

The probability of obtaining a test statistic at least as extreme as the one that was actually observed, assuming that the null hypothesis is true.
