• A)6.8 mV
• B)5.2 mV
• C)3.6 mV
• D)8.4 mV
• E)10 mV

Negatively Linearly Related

A relationship between two variables where an increase in one variable results in a decrease in the other, represented by a downward sloping line on a graph.

Linear Relationship

A linear relationship describes a straight-line relationship between two variables, where a change in one variable is proportional to a change in the other.

Significance Level

The probability of rejecting the null hypothesis in a statistical test when it is actually true, commonly denoted as alpha.
