Textbook Problem

A researcher would like to know which factors are most important to people who are buying a new car. A sample of *n =* 200 customers between the ages of 20 and 29 are asked to identify the most important factor in the decision process:

Performance, Reliability, or Style. The researcher would like to know whether there is a difference between the factors identified by women compared to those identified by men The data are as follows:

Observed Frequencies of Most Important Factor According to Gender | ||||

Performance | Reliability | Style | Totals | |

Male | 21 | 33 | 26 | 80 |

Female | 19 | 67 | 34 | 120 |

Totals | 40 | 100 | 60 |

**a.**State the null hypotheses.**b.**Determine the value for*df*for the chi-square test.**c.**Compute the expected frequencies.
