The correlation coefficient measures the relationship between the two variables

The correlation coefficient is 0.234

<h3>How to determine the correlation coefficient</h3>

The formula of correlation coefficient is:

$r = \frac{1}{n - 1} * \sum{(\frac{x - \bar x}{\sigma_x})*(\frac{y - \bar y}{\sigma_y})$

Using the dataset from the complete question, we have:

$r = \frac{1}{5 - 1} * 0.9375$

Evaluate the difference

$r = \frac{1}{4} * 0.9375$

Evaluate the quotient

$r = 0.234375$

Approximate

$r = 0.234$

Hence, the correlation coefficient is 0.234
