Textbook Problem

The researchers cited in the previous problem also examined the weight/salary relationship for men and found a positive relationship, suggesting that we have very different standards for men than for women (Judge & Cable. 2010). The following arc data similar to those obtained for working men. Again, weight relative to height is coded in five categories from 1 = thinnest to 5 = heaviest. Income is recorded as thousands earned annually.

**a.** Calculate the Pearson correlation for these data.

**b.** Is the correlation statistically significant? Use a two-tailed test with α = .05.

Weight (X) |
Income (Y) |

4 | 156 |

3 | 88 |

5 | 49 |

2 | 73 |

1 | 45 |

3 | 92 |

1 | 53 |

5 | 148 |

**a**.

To determine

The Pearson correlation of the given data.

Explanation

**Given info:**

The given data are shown below,

Weight(X) | Y |

4 | 156 |

3 | 88 |

5 | 49 |

2 | 73 |

1 | 45 |

3 | 92 |

1 | 53 |

5 | 148 |

**Calculation:**

Formula to calculate the Pearson correlation is,

Where co variability of the variable x and y is

Mean of the variable

Thus the mean of the variable

Mean of the variable

Thus the mean of the variable y is 88

For calculating

**b**.

To determine

**To explain:** The correlation is statistically significant or insignificant using two tail test at 5% level of significance.
