The Slope of a Curved Line Differs from That of a Straight

question 116

Multiple Choice

The slope of a curved line differs from that of a straight line in that

• A)the numerical value of the slope of a straight line is different at every point but is the same at every point for a curved line.
• B)the numerical value of the slope of a straight line is always higher than the numerical value of the slope of a curved line.
• C)the numerical value of the slope of a curved line is different at every point but is the same at every point for a straight line.
• D)the numerical value of the slope of a curved line is an irrational number, but the numerical value of the slope of a straight line is always a rational number.
• E)straight lines are more realistic, but curved lines are not descriptively accurate for the real world.

Definitions:

Standard Error

Describes a statistical measure that estimates the accuracy with which a sample represents a population.

Critical Value

A point on the scale of the test statistic beyond which we reject the null hypothesis; it's determined by the significance level.

Null Hypothesis

A statement suggesting that there is no significant difference or relationship between specified populations, any observed difference being due to sampling or experimental error.

Null Hypothesis

A statement in statistical hypothesis testing that assumes no effect or no difference between phenomena or populations.
