baherus [9]

Answer:

<em>H₀</em>: The voting preference of men and women are not different.

<em>Hₐ</em>: The voting preference of men and women are not different.

Step-by-step explanation:

A hypothesis test for two proportions can be used to determine whether the preference of men differ from women in case of voting.

A Chi-square test contingency table can be used to perform the test.

The hypothesis can be defined as:

<em>H₀</em>: The voting preference of men and women are not different.

<em>Hₐ</em>: The voting preference of men and women are not different.

The test statistic is:

\chi^{2}=\frac{Row\ total\times Column\ total}{N}

Decision rule:

If the <em>p</em>-value of the Chi-square test statistic is less than the significance level <em>α</em> = 0.05 then the null hypothesis will be rejected. And if the <em>p</em>-value is more than the significance level then the null hypothesis will not be rejected.
