For a data set of chest sizes (distance around chest in inches) and weights (pounds) of ten anesthetized bears that were measured, the linear correlation coefficient is \( r = 0.662 \). Use the table available below to find the critical values of \( r \).| Number of Pairs of Data \( n \) | Critical Value of \( r \) ||---------------------------------|---------------------------|| 4 | 0.950 || 5 | 0.878 || 6 | 0.811 || 7 | 0.754 || 8 | 0.707 || 9 | 0.666 || 10 | 0.632 || 11 | 0.602 || 12 | 0.576 |This table provides critical values for the correlation coefficient \( r \) based on the number of pairs of data \( n \). Compare your calculated \( r \) value with the critical value from the table to determine the significance of the correlation.

We have given that the linear correlation coefficient r = 0.662
