Literacy rate is a reflection of the educational facilities and quality of education available in a country, and mass communication plays a large part in the educational process. In an effort to relate the literacy rate of a country to various mass communication factors, a researcher has proposed to relate literacy rate (* y*) to the following variables: number of daily newspaper copies (per 1000 population)(

*), number of radios (per 1000 population)(*

*x1**), and number of TV sets (per 1000 population)(*

*x2**). Table 3 shows the data for a sample of 10 countries.*

*x3*Table 3

Country | Newspapers | Radios | TV sets | Literacy Rate |

Malaysia | 280 | 266 | 228 | 0.98 |

Singapore | 142 | 230 | 201 | 0.93 |

Vietnam | 10 | 114 | 2 | 0.25 |

Brunei | 391 | 313 | 227 | 0.99 |

Thailand | 86 | 329 | 82 | 0.79 |

Cambodia | 17 | 42 | 11 | 0.72 |

Myanmar | 21 | 49 | 16 | 0.32 |

Indonesia | 314 | 1695 | 472 | 0.99 |

Philippines | 333 | 430 | 185 | 0.99 |

Laos | 91 | 182 | 89 | 0.82 |

- Use Microsoft Excel to produce Analysis of Variance table for the multiple linear regression and state the model.
- At a = 0. 05 test whether the model generated in (a) is fit or not.
- Calculate the 95% confidence interval for the coefficient value for newspapers.
- Interpret the value of
*R*gathered in (a).^{2} - Based on your answer in (b), draw a conclusion on the linear relationship between literacy rate and the three factors.
