Question

You may need to use the appropriate technology to answer this question.

Consider the following data on *x* = weight (pounds) and
*y* = price ($) for 10 road-racing bikes.

Brand | Weight | Price ($) |
---|---|---|

A | 17.8 | 2,100 |

B | 16.1 | 6,250 |

C | 14.9 | 8,370 |

D | 15.9 | 6,200 |

E | 17.2 | 4,000 |

F | 13.1 | 8,500 |

G | 16.2 | 6,000 |

H | 17.1 | 2,580 |

I | 17.6 | 3,300 |

J | 14.1 | 8,000 |

These data provided the estimated regression equation

*ŷ* = 28,458 − 1,433* x*.

For these data, SSE = 7,312,286.84 and SST = 51,956,800. Use the
*F* test to determine whether the weight for a bike and the
price are related at the 0.05 level of significance.

State the null and alternative hypotheses.

*H*_{0}: *β*_{1} ≥ 0

*H*_{a}: *β*_{1} < 0

*H*_{0}: *β*_{0} = 0

*H*_{a}: *β*_{0} ≠ 0

*H*_{0}: *β*_{0} ≠
0

*H*_{a}: *β*_{0} = 0

*H*_{0}: *β*_{1} ≠ 0

*H*_{a}: *β*_{1} = 0

*H*_{0}: *β*_{1} = 0

*H*_{a}: *β*_{1} ≠ 0

Find the value of the test statistic. (Round your answer to two decimal places.)

Find the *p*-value. (Round your answer to three decimal
places.)

*p*-value =

State your conclusion.

A) Reject *H*_{0}. We conclude that the
relationship between weight (pounds) and price ($) is
significant.

B) Do not reject *H*_{0}. We conclude that the
relationship between weight (pounds) and price ($) is
significant.

C) Reject *H*_{0}. We cannot conclude that the
relationship between weight (pounds) and price ($) is
significant.

D) Do not reject *H*_{0}. We cannot conclude that
the relationship between weight (pounds) and price ($) is
significant.
