Question

this table displays
the relationship
between two
variables, x and y,
showing the
corresponding y-
values for given x-
values.

x-value y-value
5 22
6 29
7 28
8 31
9 37

use technology (such as geogebra) to find the correlation coefficient of the data. round your r - value to two
decimal places, if necessary.

(1 point)

○ 0.93
○ 0.94
○ 0.90
○ 6.40

Explanation:

Step1: List data pairs

$(5,22), (6,29), (7,28), (8,31), (9,37)$

Step2: Calculate correlation coefficient

Using technology (e.g., GeoGebra) to compute the Pearson correlation coefficient $r$ for the paired data.

Step3: Round to two decimals

The calculated $r$ rounds to 0.94.

Answer:

B. 0.94
