Suppose you computed r=−0.142 using a sample size of 22 data points. Using the critical values table below, determine if the value of r is significant or not.

Degrees of Freedom | Critical Values |
---|---|

19 | 0.433 |

20 | 0.423 |

21 | 0.413 |

22 | 0.404 |

23 | 0.396 |

24 | 0.388 |

Select the correct answer below:

r is significant because it is between the positive and negative critical values.

r is significant because it is **not **between the positive and negative critical values.

r is **not** significant because it is between the positive and negative critical values.

r is **not** significant because it is **not **between the positive and negative critical values.
