## If you pay more in tuition to go to a top business school, will it necessarily result in a higher probability of a job offer at graduation?

If you pay more in tuition to go to a top business school, will it necessarily result in a higher probability of a job offer at graduation? Let y equals percentage of graduates with job offers and x equals tuition cost; then fit the simple linear model, E(y) = B0 + B1 * x , to the data below. Is there sufficient evidence (at alpha = 0.10 ) of a positive linear relationship between y and x?

School | Annual_tuition ($) | %_with_Job_Offer |

1 | 39673 | 92 |

2 | 39517 | 81 |

3 | 39301 | 93 |

4 | 39166 | 96 |

5 | 38429 | 88 |

6 | 38359 | 91 |

7 | 37608 | 96 |

8 | 36888 | 96 |

9 | 36484 | 82 |

10 | 36282 | 89 |

other Questions included;

a) Give the null and alternative hypotheses for testing whether there exists a positive linear relationship between y and x?
