Answer 1

To determine the correlation coefficient of the provided data, we typically would calculate the Pearson correlation coefficient (r).

Your data points are:

- \( x = [1, 3, 5, 7, 9] \)
- \( y = [13, 43, 51, 76, 81] \)

Using a statistical calculator or software available, we can find the correlation coefficient \( r \).

Calculating it, we obtain:

\[
r \approx 0.973
\]

This indicates a strong positive correlation, as the value is close to 1.

Based on the options provided, the correct response is:

**0.97300135; strong**
