The marketing manager of a large supermarket chain would like to determine the effect of shelf space (in feet) on the weekly sales of international food (in hundreds of dollars). A random sample of 12 equal –sized stores is selected, with the following results:

Shelf Space (X) | Weekly Sales(Y) |

10 | 2 |

10 | 2.6 |

10 | 1.8 |

15 | 2.3 |

15 | 2.8 |

15 | 3 |

20 | 2.7 |

20 | 3.1 |

20 | 3.2 |

25 | 3 |

25 | 3.3 |

25 | 3.5 |

**Find the equation of the regression line for these data. What is the value of the standard error of the estimate? Place your answer, rounded to 3 decimal places, in the blank. Do not use a dollar sign. For example, 0.345 would be a legitimate entry.****Find the equation of the regression line for these data. What is the value of the coefficient of determination?
