Reference no: EM131029036

A survey to explore the relationship between voters' church-attendance patterns and their choice of presidential candidate was reported in the Riverside Press-Enterprise prior to the 2004 presidential election. Voters were asked how often they attended church services and which of the two major presidential candidates (George W. Bush or John Kerry) they intended to vote for in the election. The results of a similar survey are contained in the following table.

Church Attendance	Bush	Kerry
More than once per week	89	53
Once per week	87	68
Once or twice per month	93	85
Once or twice per year	114	134
Seldom/never	22	36

a. Is there sufficient evidence to indicate dependence between reported frequency of church attendance and choice of presidential candidate in the 2004 presidential election? Test at the .05 level of significance. Place bounds on the attained significance level.

b. Give a 95% confidence interval for the proportion of individuals who report attending church at least once per week.
