**Question: ** Week 4 Activity6, Part C: non-parametric version of the single factor ANOVA

**Question: **A researcher sampled 100 women from a medical record database and identified their smoking status and parity. Use the 5 steps of hypothesis testing to determine whether pregnancy and smoking status are independent.

Smoking Status | Parity | |

Before Pregnancy | No children | Children |

Nonsmoker | 20 | 20 |

Smoker | 5 | 55 |

**Question: **A medical student surveys adults to determine if gender and seat belt use are independent. Use the 5 steps of hypothesis testing to determine whether gender and seat belt use are independent.

Seat belt use | Gender M | F |

Belt | 70 | 60 |

No belt | 30 | 40 |

**Question: **A researcher collected daily sodium intake and systolic blood pressure readings on 12 patients. Obtain the regression equation from SPSS and include the table you used for the data. Use the 5 step hypothesis testing approach to determine if the regression equation is significant at alpha = 0.05. What would be a likely blood pressure for a person with a sodium intake of 6.3: 7.6?

Sodium | SBP |

6.8 | 154 |

7 | 167 |

6.9 | 162 |

7.2 | 175 |

7.3 | 190 |

**Question: **Two health inspectors rate 11 hospitals on cleanliness. Determine whether their rankings are comparable, using the appropriate nonparametric test and the 5 steps of hypothesis testing.

Inspector 1 | Inspector 2 |

2 3 2 3 1 4 5 3 1 3 4 | 1 3 3 2 2 5 4 2 1 4 3 |

**Question: **A medical informatics manager reviews sick day use in her department. She identifies that employees in her small department used the following amount of sick time in the past year:

Men: 5,10,2,0,6,4,5,15

Women: 8,9,3,5,0,4,15

The statistician indicated she should use a nonparametric test to determine if there is a difference in sick time use between the men and women in her department. Use the 5-step approach to hypothesis testing and alpha=0.05 to determine if there is a difference.
