Question

(Scatter Plots MC)

The relationship between the amount of time a basketball player spent practicing the day before a game and the number of points he scored in the game is graphed on the scatter plot shown.

scatter plot titled basketball players, with the x axis labeled time practicing in minutes and the y axis labeled points scored with points at 0 comma 10, 10 comma 15, 15 comma 18, 25 comma 25, 30 comma 28, 30 comma 30, 45 comma 35, 70 comma 40, 70 comma 45, 80 comma 45, 90 comma 50, and 120 comma 60

Describe the type and degree of association in the scatter plot and what it means in terms of the time the player spent practicing and the number of points he scored in the game.

As the time a basketball player practices increases, the number of points scored in a game decreases with a weak linear association.
As the time a basketball player practices increases, the number of points scored in a game decreases with a weak nonlinear association.
As the time a basketball player practices increases, the number of points scored in a game increases with a strong linear association.
As the time a basketball player practices increases, the number of points scored in a game increases with a strong nonlinear association.

Answer 1

Answer: The real answer is (A) As the time a basketball player practices increases, the number of points scored in a game increases with a strong linear association.

Explanation:

I graphed the coordinates in a coordinate plane and the line is linear and has a very strong association.

I know the line is linear because the way the coordinates are, looks like a line.

I can tell the coordinates have a strong association because they are grouped closely together.

Anyway, if you still don't fully trust my answer here is the graphed coordinates:

If you need more proof, here is the definition of linear coordinates and strong association from my lesson:

Linear Association Definition:

A scatter plot with a linear association shows a pattern that can be described by a straight line.

Strong Association Definition:

A scatter plot with a strong association has points that appear to follow a single path, whether straight, curved, or bending all over the place. The stronger the association, the more closely the points are grouped together.

Anyway hope y'all have a great day. I bit my tongue lol.
