Question

Surya gave each family member a playlist, and their rankings were compared to song release years. The regression line has a slope of

0.096−0.096. What does the negative slope indicate?
a) As song release years increase, rankings decrease.
b) As song release years increase, rankings increase.
c) No correlation between song release years and rankings.
d) Inconsistent relationship between song release years and rankings.

Answer 1

A negative slope indicates that as song release years increase, rankings decrease.

Step-by-step explanation:

A negative slope means that two variables are negatively related; that is, when x increases, y decreases, or when x decreases, y increases.

Graphically, a negative slope means that, as the line on the line graph moves from left to right, the line falls. The altitude-air density relationship, shown in Figure A4 later in this appendix, has a negative slope.

We will learn that price and quantity demanded have a negative relationship; that is, consumers will purchase less when the price is higher.
