Alya claims that the scatterplot shows a linear correlation. Enrique claims that the scatterplot has no correlation.
On a graph, points are grouped to form a horizontal cluster.
Which statement about their claims is true?
Alya is correct because the scatterplot clusters about a line with a slope of zero.
Alya is correct because as the x-values increase, the y-values remain the same.
Enrique is correct because the scatterplot clusters about a curve.
Enrique is correct because as the x-values increase, the change has no effect on the y-values.

Given : Alya claims that the scatterplot shows a linear correlation. Enrique claims that the scatterplot has no correlation.
On a graph, points are grouped to form a horizontal cluster.
To Find :
Which statement about their claims is true?
Alya is correct because the scatterplot clusters about a line with a slope of zero.
Alya is correct because as the x-values increase, the y-values remain the same.
Enrique is correct because the scatterplot clusters about a curve.
Enrique is correct because as the x-values increase, the change has no effect on the y-values.
Solution:
Alya is correct because the scatterplot clusters about a line with a slope of zero. FALSE
Slope of zero means no correlation , as there is no impact of change in one variable to another variable
Alya is correct because as the x-values increase, the y-values remain the same. FALSE
As x-values increase, the y-values remain the same Hence no correlation
Enrique is correct because the scatterplot clusters about a curve. FALSE
scatterplot does not clusters about a curve but a horizontal line
Enrique is correct because as the x-values increase, the change has no effect on the y-values. TRUE
As the x-values increase, the change has no effect on the y-values Hence No correlation
