Question

The table below shows the values of y for different values of x:

x 7 8 9 10 11 12 13
y 13 10 7 6 5 3 0


The correlation coefficient for the data is −0.9847. Which statement is true about the data in the table?

There is no relationship between x and y.
There is a weak negative relationship between x and y.
There is a strong positive relationship between x and y.
There is a strong negative relationship between x and y.

Answer 1

D.. Just took . the test

Explanation:

Answer 2

There is a strong negative relationship between x and y

Explanation:

we know that

The correlation coefficient r measures the direction and strength of a linear relationship. It can take a range of values from +1 to -1.

Values between 0.7 and 1.0 (-0.7 and -1.0) indicate a strong positive (negative) linear relationship

In this problem

The correlation coefficient for the data is −0.9847

therefore

Is a strong negative correlation
