\(\text{5}\) | \(\text{5}\) | \(\text{25}\) | \(\text{25}\) | \(\text{56,25}\) | \(\text{0,81}\) |

\(\text{8}\) | \(\text{8}\) | \(\text{64}\) | \(\text{64}\) | \(\text{20,25}\) | \(\text{15,21}\) |

\(\text{13}\) | \(\text{3}\) | \(\text{39}\) | \(\text{169}\) | \(\text{0,25}\) | \(\text{1,21}\) |

Therefore, the correlation between \(x\) and \(y\) is negative but weak.
