###### Question details

Consider the following bivariate data.

Point | A | B | C | D | E | F | G | H | I | J |

x |
1 | 4 | 6 | 6 | 4 | 3 | 7 | 4 | 5 | 0 |

y |
7 | 6 | 3 | 4 | 0 | 6 | 2 | 0 | 6 | 3 |

(a) Construct a scatter diagram of the given bivariate data. (Do
this on paper. Your instructor may ask you to turn in this
work.)

(b) Calculate the covariance. (Give your answer correct to two
decimal places.)

(c) Calculate *s _{x}* and

*s*. (Give your answers correct to three decimal places.)

_{y}s_{x} |
= |

s_{y} |
= |

(d) Calculate *r* using formula 13.2. (Give your answer
correct to two decimal places.)

(e) Calculate *r* using formula 13.3. (Give your answer
correct to two decimal places.)
